The Mice have made recurring appearances in Garfield's TV shows.
In Garfield and Friends, Floyd is the main mouse. While initially an antagonist, taking advantage of Garfield's refusal to chase mice by bringing his mice brethren to feast in Jon's house, he and Garfield quickly became good friends. Floyd is not shown frequently in the show, appearing at most twice in any given season, but he made the most of his limited screen time, often co-starring with Garfield whenever he does appear. He even got one episode bearing his name, and therefore, was centered around him. He has a recurring gag where he tries to convince Garfield to allow him on the show more often.
Other mice have made appearances in various episodes, sometimes with Floyd. Tyrone and Irwin were friends of Floyd's, the latter of whom desired to be a cat before Garfield eventually talked him out of it. April is a mouse who is also Floyd's wife. A mouse named Riff tortured Garfield when it was believed that his mother got eaten by the cat, even getting a muscular mouse named Max to force answers out of him, to no avail.
Another aspect of Garfield and Friends are the Quickies. Mice have appeared in a few Quickies, albeit not very many (A total of four). The Quickies Loretta and Swiss Cheese starred Garfield and mice exclusively, Timeshare and Rodent Rebellion included other characters, (Birds and Jon respectively).
While mice have appeared rather infrequently in Garfield and Friends, the same cannot be said when it comes to The Garfield Show. Mice have appeared many times in The Garfield Show, the main one being named Squeak. Squeak's roles have varied greatly. Sometimes, he gets a leading role, co-starring with Garfield from time to time. Other times, he gets a solid role, a major character that plays a decent part in a given episode, and occasionally, he only appears briefly, one or two scenes at most.
Squeak is not the only mouse to appear in The Garfield Show, but he is the most recurring. Humphrey, later Irv, appeared at least once every season, but like Floyd, he appeared twice at most during a season. Biff and Emily are a couple, Biff being known for his love of working out, (and is therefore extremely buff) and Emily commonly wishing he would be more lenient to his fellow mice. Other mice like Max, Mary Margaret, and Packy appeared once, though mice resembling Packy (That is, chubbier than Squeak) have appeared here and there along with Squeak and/or other mice.
Even in Garfield Originals have mice made sprinkled appearances. Their major appearance came in Mice Phobia, five scenarios that are based upon Jon's fear of mice, and Garfield taking advantage of this. They appeared sparingly in several other episodes, doing things such as waking Garfield up with an electric guitar, dancing in front of Jon, unsuccessfully using a treadmill, and tickling Garfield's nose.
Garfield and Friends[]
Mice made scattered appearances in Garfield and Friends. Floyd is the most recurring of the bunch, and others have appeared in a handful of Quickies.
Floyd[]
Main Article: Floyd
Floyd is the main mouse character in Garfield and Friends. While he was originally shown to be an antagonist in his first appearance, calling his mouse friends to Jon's house upon learning that Garfield does not eat mice, he and Garfield typically interact as friends, acting cordially to each other and even helping each other out of binds from time to time. A recurring gag he has in the show is the desire for more screen time, as he only appears once or at most twice in any given season.
Riff[]
Main Article: Riff
Riff is a young mouse, who was temporarily separated from his mother, when she was searching for food in A Jarring Experience episode.
April[]

Tyrone[]
Main Article: Tyrone
Tyrone is a mouse friend of Floyd's who appeared for only one episode. While Floyd took him on a tour of the house, Tyrone became surprised by Floyd telling him about Garfield's unwillingness to chase mice. Tyrone was initially unbelieving, until he sees Garfield's laziness firsthand. He is not keen on this and tries making Garfield chase him, but the cat refused. Eventually, Garfield does chase him after he made a sandwich with the cat's paw as an ingredient, but after Garfield stops, Tyrone becomes furious with him, while Floyd tries playing peacemaker and tells Tyrone to lay off. Later, Garfield, after getting nagged by Jon to rid the house of both mice, sees an ad for Binky's circus. Jon brings home a lion, which scares the mice away.
Irwin[]

Swiss Cheese[]
Garfield shoves a piece of Swiss cheese into a mouse hole. When he hears chewing, he uses billows to blow air into the cheese, inflating the mouse like a balloon.
Loretta[]
Garfield is in a bad mood, and he kicks a mouse out of his way. The mouse protests and threats to get his sister, Loretta, to pound Garfield. Garfield accepts the challenge, thinking that a fight will cheer him up, unaware that Loretta's tail alone is bigger than he is.

The Garfield Show[]
Mice are a lot more prevalent in The Garfield Show. While Floyd only appeared at most twice a season of Garfield and Friends, the mice appear quite frequently in The Garfield Show.
Characters[]
Squeak[]
Main Article: Squeak
Squeak is the main mouse character in The Garfield Show. While he made his first appearance in the comics, he is more closely associated with The Garfield Show. Like his predecessor, Floyd, Squeak is a good friend to Garfield, but he is also quite fond of Odie as well. He is often more than willing to give a helping hand to either one of them whenever they may need it, and has even helped save their lives on occasion. However, he is not afraid to stand up for himself or others when needed, even against Garfield. Despite this, he is very loyal to both Garfield and Odie and always shows up when he is needed, and even at times when he is not.
Humphrey[]
Main Article: Humphrey
Humphrey, also known as Irv in later seasons, is one of Squeak's mouse friends. He is taller and skinnier than most of the mice in Jon's home, and also has a couple of buckteeth. Like Squeak, he is a loyal to Garfield and his friends, mostly Squeak. Some examples: he helped Squeak try to clear Garfield's name in The Six-Can Solution and told Squeak about the raccoon situation in Into the Wild: Where Eagles Don't Dare. However, like Floyd before him, he did not get much screen time, appearing only a few times per season (though he never complained to Garfield about it the way Floyd did in Garfield and Friends).
Biff[]
Main Article: Biff (mouse)
Biff is a recurring mouse who loves to work out. As such, he is extremely buff, and he is also shown to want to get the other mice buff as well (mostly to allow them to better defend themselves against threats). Sometimes, he can get a bit hard on his fellow mice, and even Garfield when Biff forced him to work out, and his girlfriend Emily did not like that. Regardless, she still loves him and the two cannot be apart for too long. He is also shown to stress eat when in a deep depression.
Emily[]
Main Article: Emily
Emily is Biff's girlfriend. She is a lot more compassionate to the other mice that Biff makes work out, and she is often concerned if Biff is working them too hard. After seeing Garfield worn out and exhausted, she dumped Biff on the spot. However, the two did soon reconcile, partially because they missed each other greatly. Like her boyfriend, she likes working out.
Packy[]
Main Article: Packy
Packy is a packrat that loves to trade stuff. He is a bit rounder than the other mice, including his cousin Squeak, and (as Squeak said) he lives down the street. His habit of trading is shown to frustrate Garfield, who got his stuff swapped out multiple times, and also inadvertently got Jon arrested when Packy swapped Jon's wallet for a neighbor's bracelet. After Odie caught Packy and got Jon freed, Squeak had a heart-to-heart with him about his bad habit. Despite Packy agreeing not to trade stuff anymore, he offers the viewer something in exchange for the remote.
Mice Roles[]
Season 1 Roles[]
Not So Sweet Sound of Music[]
Garfield and Squeak watch TV together, and are both determined to get rid of Jon's old accordion when the latter brings it home (Though Garfield more so than Squeak). The two devise a plan to be rid of the instrument. Squeak appears in front of Jon and Odie, and a terrified Jon tells Odie to chase him. Odie does so, and Garfield uses the distraction to throw the accordion away. With the accordion gone, Garfield and Squeak enjoy some peace and quiet in the former's bed, both ready to take a nap when Jon barges in to serenade Garfield to sleep with a song from the accordion. Squeak would not appear again until very late in the episode.
After an incident that left Garfield bandaged and bedridden for a couple of weeks, Squeak consoles him and gives him news that the accordion will not play anymore. This pleases the fat cat, until he learns that as a replacement, Jon got himself a set of bagpipes, which he deems to be worse than the accordion.
Catnap[]
When what seems like a burglar arrives at the house, Garfield tells Odie to face it. The cowardly canine retreats, with Garfield replying that he has the courage of a mouse. Squeak takes offense to this, but still gives Garfield some advice when asked. The mouse recommends a mousetrap, which is behind the refrigerator. Garfield uses it, it works perfectly, and Squeak enjoys the spectacle. He also was there when the burglar tried to get in through the upstairs window, though Garfield did most of the heavy-lifting when it came to deterring the robber.
Later on, after a brief pep talk from Garfield, Squeak and the pets work together to set up a trap. Using a roller skate (that Squeak placed) and a trunk at the foot of the basement stairs, (Odie's contribution) they manage to capture the burglar in said trunk, only for all three of them to find out that the "burglar" was Jon, who had forgotten his keys. They return upstairs, only to be shocked to find out the real burglar stole everything in the house.
Fame Fatale[]
A famous cat who looks exactly like Garfield, Sir Leo, is staying with him to get some rest and relaxation. Garfield decides to take his place and, after a day of realizing that being famous is not all it is cracked up to be, begs Sir Leo to switch back with him, but the celebrity cat refuses. Garfield then tries to tarnish Leo's reputation, and he does so by dancing with Squeak and some of his rodent friends in front of the mob of fans. Squeak and his fellow mice charge at the crowd and scare them off, and as a thank you, Garfield presents them a pile of cheese.
Caroling Capers[]
Garfield is trying, and failing, to sing Christmas carols to his neighbors for food, while also watching Odie and Nermal do the same thing with great success. He decides to add some backup singers, and goes back to his shed and gets some mice--including Squeak and Humphrey--to sing with him, so long as the rodents get first claim on cheese. After practicing, the cat and mice attempt to sing "Jingle Bells" for a neighbor, who just so happens to have a fear of mice and attacks them with a broom. After escaping with their lives, the mice quit on the spot.
Neighbor Nathan[]
Jon tells Garfield to be nice to Odie before leaving for a trip, but the cat goes ahead with a cruel prank on the pup. Squeak passes by and witnesses this but says nothing at the moment. Garfield tricks Odie into believing that puppies are outlawed, causing the pup to run panicked out of the house. Garfield laughs at his joke, but Squeak scolds him for it. The cat, however, pays him no mind and, seeing this, Squeak leaves.
Later on, as Garfield raids the fridge, Squeak tells him that he's going to use Jon's computer and asks if Odie has returned. Garfield admits that he has not, so he tries to bring him home himself, albeit with no success. He heads into the office--deeply missing Odie--and updates Squeak about him, and he admits that he does not know why the pup scorned him. Squeak answers his question with videos of Garfield's various pranks and abuse to Odie, and Garfield starts to understand Odie's choice.
However, Odie is about to be turned into a cockroach by Nathan. In desperation, he lets out a howl for help, and Squeak assumes that Odie's in trouble. He and Garfield go and check it out, and see Odie shackled to a table with a laser pointed at himself. Garfield devises a plan and as Squeak distracts Nathan by ringing the doorbell, Garfield frees Odie and takes him home.
After returning, Squeak celebrates their success, and Odie confronts Garfield about something the latter said as they left Nathan's lab. Before Garfield can address this, Squeak announces that Garfield will be nice to Odie for two weeks. Garfield agrees to it, if only for one week, and Odie is appreciative.
Season 2 Roles[]
Which Witch[]
Squeak had a brief cameo in this episode. After Garfield brought the twins home from the house of Mrs. Cauldron, Squeak can be seen sitting on a trash can.
Odie for Sale[]
After a prank from Garfield went haywire, Odie is sold to a lawyer during Jon's garage sale. Garfield tells Squeak about it and also explains that until he gets Odie back, Jon will not feed him. Garfield asks if Squeak's mouse network can find out where Odie is, and Squeak, feeling bad for Odie and very loyal to the pets, gets on the case. After getting the information from his rodent friends, Squeak gives Garfield the lawyer's address, the cat heads out to bring the pup home.
Everything's Relative[]
Jon and Doc Boy are stuck with Aunt Ivy and the twins, Drusilla and Minerva. Jon asks when Aunt Ivy is leaving, and she expresses that she has a mouse infestation, as well as her hatred of mice. This gives Garfield an idea. Using Odie to distract the twins, he goes to Squeak for help, who refuses to take Aunt Ivy. Garfield explains his plan and leads several mice out of the kitchen in Pied Piper fashion. Aunt Ivy flees in terror, and the twins leave also. Garfield then leads the mice outside where he thanks them for their help.
Honey, I Shrunk the Pets[]
Odie rescued a shrunken Garfield from a flock of pigeons, and then went to Squeak for help. Odie shows Garfield to Squeak and the three friends soon learn the reason for Garfield's diminishing: a beam coming from a house across the street. Garfield hurries to fix this, despite Squeak telling him to take caution crossing the street, and quickly gets stuck in traffic.
When a garbage truck comes Garfield's way, Squeak kicks Odie into action. Riding the pup like a jockey on a horse, Squeak swoops down and saves Garfield just in time. Odie and his friends cross the street mostly unharmed, and Garfield devises a plan to get inside the house where the beam came from, leaving Odie and Squeak behind.
After Garfield returns to his normal size, Squeak and Odie express how happy they are to have him back to normal. Garfield thanks the mouse, but still seems distracted by something. Squeak asks him about it, and Garfield dreams about using the beam that shrunk and grew him to grow food to gigantic proportions.
History of Cats[]
Garfield tells the history of cats. He elaborates about the myth of cats eating mice and explains cats contributions throughout history. They invented cheese, painted the Mona Lisa, and helped Beethoven compose his famous 5th Symphony. All of this slowly angers Squeak and the other mice, until they finally snap and attack Garfield, irate at his embellishing.
The mice tackle Garfield and demand that he tells the truth about the aforementioned events, or else the mice will inform Jon about how much money Garfield spent on pizza last month. Garfield complies and retells his prior three stories, except giving mice the credit instead of cats. The mice are appreciative and thank Garfield before heading out.
After the mice go, Garfield tells Odie that he has no intention of sending the pro-mice to the network, instead planning on cutting that out through editing. The two of them walk to the mailbox together, where Garfield sends his edited version to the executives and throws the full version into the trash, but after they go, several mice, Squeak among them, sneakily swap the videos.
Pirate Gold[]
During a dismal, drizzly day, Garfield imagines himself as a pirate after watching a TV show about pirates. Odie and Squeak join him on the adventure, Squeak becoming Garfield's first mate who also steers the ship. They eventually come to an imagined island and encounter three dogs in their treasure. Garfield sweeps up the dogs in his imagination and sends them fleeing in terror from his pirate band, and Garfield, Odie, and Squeak divvy up the treasure--which is the food in the refrigerator.
Detective Odie[]
Early one morning, a strange-looking mouse come out from Jon's dresser in his bedroom and takes his wallet from there. He runs across to the street into a neighbor's house and trades Jon's wallet with the neighbor's bracelet. The neighbor, Mrs. Schmidlap, arrives, and the mouse hides, going unnoticed by her.
Later that day, Jon, Garfield, and Odie are up, the fat cat sipping a cup of coffee. Odie wants to play fetch, and Garfield sets his coffee down and does so, if only to get Odie out of his fur. He returns to his coffee, only to realize that someone swapped his coffee with a rubber ducky. He angrily looks around, and Squeak asks him if something is missing. The mouse quickly finds out that his cousin Packy is running amok. Just then, Packy arrives offering to trade Garfield something for the ducky. The cat demands his coffee and goes back to bed, only to find that Packy swapped his bed out, too.
Soon after, two detectives arrive at Jon's house and arrest him for the supposed theft of Mrs. Schmidlap's bracelet. Odie sees this and runs to get help, while Garfield is still inside demanding his bed back from Packy. He gets it back and tries to sleep, leaving Odie on his own to help his owner. Remembering something Jon said, Odie decides to investigate.
He follows the scent from Jon's dresser to Packy and quickly apprehends him. He shows the culprit to Garfield and Squeak, who were watching the news report about it on TV. The pets and mice race to the police station to clear Jon's name and get him free, which is precisely what happens. Afterwards, Squeak has a heart-to-heart with his cousin, who promises to stop trading stuff, only to break the fourth wall by offering something to the viewer in exchange for the TV remote.
Mind Over Mouse[]
This was one of Squeak's more major roles. Garfield schemes to steal some ice cream but Squeak tells him not to worry, since some ice cream will spill out anyway. Sure enough, that happens, Squeak admits that he has the power to see the future. Garfield does not believe it, until another prediction Squeak makes comes true. Garfield goes to Squeak, wondering how he does it, and instead of answering, Squeak says a few more predictions before retreating into his hole when Jon came in. Garfield eventually leaves.
After Garfield left, Squeak tells and shows the viewers how he does it: he has been watching episodes of The Garfield Show in advance and thus, is able to tell what will happen next. He returns to the kitchen and agrees to feed Garfield his predictions so that the fat cat can become known as "the cat that can predict the future." Jon learns about Garfield's new ability and the latter soon becomes famous, even appearing on a TV game show where he has a chance to win $1,000,000. As Jon and the pets get ready for it, Squeak chooses to stay behind, for now.
The reason Squeak stayed behind is because he did not finish the show yet. As he tries fast forwarding to the end, he accidentally deletes it, and its rerun is preempted for the game show Garfield will be playing. Horrified, he hurries down to the TV station. On stage, Garfield is tasked to predict the top card of a shuffled 52-card deck. Garfield, without Squeak to help him, decides to guess, when Squeak arrives and tells Garfield to try the Jack of Diamonds, only to find out that Garfield's first guess was correct. Jon is promptly dumped into rancid cheese as punishment for failing the game and they all return home.
Later that night, Garfield is punished with being fed rancid cheese for a year, and he asks Squeak how he was able to make those predictions. Squeak comes clean about how he has been watching reruns of the show, which infuriates Garfield. He chases after Squeak, who flees and frantically apologizes.
Parrot Blues[]
Jon is caring for his boss's pessimistic parrot, Paxton. Garfield pays him no mind and chooses to sleep instead, but is woken up by the sound of crying mice. Indeed, downstairs, a small group of mice cry as Paxton tells them about what ingredients they're putting in cheese and how they are building better mousetraps until Garfield grabs him and takes him away.

Squeak tries convincing Garfield to go and save Lyman.
Long Lost Lyman Part 2[]
Odie is howling, mourning the disappearance of his old master, Lyman, well into the night, waking Garfield and Squeak--who speaks on behalf of the other mice--up.

Squeak and his friends smile after the former subdued the Zabadu.
Regardless, Garfield decides to go and battle a monster, the Zabadu, using his imagination to travel there, and he takes Odie and Squeak along with him. They land in Franistan and find the Zabadu, resulting in a chase. However, Squeak is able to it off because it has a fear of mice. The fantasy ends with Odie hugging someone he thinks is Odie, but is instead Jon, who was woken up by Garfield's fantasy. Squeak quickly hides and watches, his eyes filled with compassion for Odie, and Jon decides to go to Franistan to rescue Lyman himself.

Squeak and his rodent friends party the day away.
The next morning, Squeak helps Garfield get his suitcase of snacks down the stairs and bids him, Jon, and Odie good-bye, promising to look over the house while they're gone. With Jon and the pets gone, the mice throw a huge party in the house, singing, dancing, and making the house their own.

Squeak asks Garfield where Odie is.
Long Lost Lyman Part 4[]
After finding Lyman and dealing with the bad guys, Garfield and Jon return home... without Odie, since Lyman decided to take his pup back. Upon Jon's and Garfield's arrival, the mice quickly stop the party and hide. Squeak secretly asks Garfield how the trip went. Garfield replies that it went well, but Squeak the asks why he seems so downtrodden, noting that Garfield looks like he lost his best friend. He finally asks where Odie is, but Garfield claims to not know anyone by that name.

Squeak watches as Lyman returns Odie home.
Squeak and the other mice realize that Odie is gone and are also quite saddened, though not nearly as much as Garfield. The doorbell rings soon afterwards, and the mice secretly watch from the staircase. Jon answers the door to see Lyman, hand-delivering Odie back where he belongs. The mice celebrate Odie's return.

Garfield begs Squeak to tell Odie who he is, but Squeak does not recognize him either.
It's About Time[]
Nermal went back in time and caused Jon to adopt him instead of Garfield, and so, Garfield's friends do not seem to recognize him. This includes Squeak. After Garfield got met with growling and barking from Odie, he begs Squeak to tell Odie who he is. Squeak, however, does not recognize him due to the altered timeline and flees in terror, claiming that cats eat mice, except for Nermal.

The mice ballerinas dance beautiful ballet.
The Control Freak[]
Garfield is sleeping outside in his lawn chair one day when he is woken up by some mice dancing ballet with the help of a radio playing music and instructions that Squeak operates. The mice dance ballet perfectly, while Garfield pays them no mind, eagerly awaiting lunch.

Later on, Garfield would stop Nathan's scheme and use the latter's mind control ray against him. He uses the radio the mice used earlier to make Nathan dance ballet, and the ballerina mice join him. Garfield and Odie watch.

The pets, Liz, and Mrs. Cauldron head out to intervene, while Squeak decides to stay behind, noting that he gets airsick.

Squeak winks to the viewers, his memory of the past events still intact.
Later on, Garfield and his friends stop the ceremony and everything is put back to normal, thanks to Mrs. Cauldron. However, she also wiped the memories of everyone who was there. While Garfield tries and fails to remember, Squeak alludes to the viewers that he still knows what happened, since he was not there to get his memory erased.

Squeak asks Garfield for a piece of pizza.
The Garfield-Only Show[]
Squeak was part of the mass of characters that left after having a blow-up with Garfield.

Garfield declines, angering the rest of the cast.
Fast Friends[]
Mrs. Ferret's speed is preventing Garfield from getting any food. After Garfield got his pizza stolen, he learns that Squeak has had the same problem, having his cheese pilfered from him. Squeak suggests getting faster, which Garfield agrees with, and Squeak tells Garfield he knows the guy to get him into shape. That guy turns out to be Nermal.

While Squeak and Nermal touch their toes, Garfield simply wiggles his toes.
The next morning, Squeak accompanies Garfield and Odie in speed training. Nermal starts out by touching his toes, and Squeak follows suit, but Garfield has Odie touch his toes for him. They then jog and prepare to race, but Mrs. Ferret beats them all in said race. Nermal calls it quits, but Garfield is determined to get faster than the ferret.
After a couple of failed attempts, Garfield, Squeak, and Odie are resigned to the fact that Mrs. Ferret is too fast, but then, they see an advertisement for a weight-gain program. Garfield buys it and plants it in a pan of lasagna, which Mrs. Ferret ingests and becomes so fat she cannot move. The three friends share some brownies, now that she cannot move.
Later on, Garfield enjoys some lasagna, unaware that the serving he was eating the laced lasagna until Squeak told him about it. Garfield himself gets too fat to move, and after Nermal arrives, he chases the kitten out of the house. Squeak and Odie watch, with Squeak confident that Garfield will lose weight in no time, so long as the fat cat chases the kitten every time Nermal annoys him.
Fitness Crazed[]

This is shown when Bruno invades and tries catching the mice, only for Biff to clean his clock and literally throw him out. The mice celebrate, thankful for the rescue. However, something Squeak says gives Biff an idea: get Garfield into shape so that he can protect the mice.
At first, Garfield refuses, but Biff denies him sweet, sugary treats, and Garfield reluctantly complies. Biff works him out hard, and even harder after catching Garfield cheating. Eventually, an exhausted Garfield looks for a way out of this, and Squeak tells him that Biff stress-eats when miserable. This gives Garfield an idea to get out of exercise.

With Biff back in action, Garfield, Odie, Squeak, Biff, and Emily go to rescue the mice Bruno captured. Upon arriving and seeing Bruno, Biff lets him have it once again, dealing with him effortlessly and freeing the mice.

Hector clamps down on Garfield's eating, and while rough at first, the cat eventually gets accustomed to it.

Squeak and Irv plead their case to an accusing Garfield.
However, after Hector notices several cans of cat food missing, Garfield is the primary suspect, and he is punished by getting stripped of his midnight snack. Determined to clear his name, Garfield accuses the mice of stealing the food, but Squeak and Irv deny touching it. Garfield leaves to find the real culprit, but the mice set out themselves to clear Garfield's name.

Squeak is shocked to find the cat food culprit: Odie.
After several unsuccessful attempts to find any trace of the food, Squeak takes extreme measures. He finds an empty can in a neighbor's trash can and hides himself in it, waiting for the true culprit to arrive, and to his shock, it turns out to be Odie. The pup grabs his can and rolls it over to the neighbor's house, where a girl is sheltering a mother cat with kittens. Squeak witnesses it all and uses this info to clear Garfield's name.

Garfield thanks Squeak for what he did, who in turn praises Odie for what he did.
