I don't know if an animation errors section on The Garfield Wiki is needed. Therefore, I think it is best to leave it open for debate.
If it helps out, here are some examples of wikis with such pages (to give an idea on how the Garfield wiki one could go):
http://transformers.wikia.com/wiki/Animation_error http://superfriends.wikia.com/wiki/Category:Production_and_animation_errors http://pixar.wikia.com/Mistakes_found_in_Pixar_films http://sailormoon.wikia.com/wiki/Animation_Errors_in_the_Sailor_Moon_anime http://theamazingworldofgumball.wikia.com/wiki/Animation_Errors/Gallery http://phineasandferb.wikia.com/wiki/Errors http://spongebob.wikia.com/wiki/List_of_continuity_errors
If you have other (suitable) examples that you think should be included, I can add them to the list.
Update: Since there doesn't seem to be any opposition to the idea (or many commenting, for that matter), and since it does look like it could work out, I've decided to close the part about whether or not it should be utilized. I will keep the links above (and again, leave it open for additions) for inspiration on how it can be done here.
