Animation Source Forums

Don't know whether anyone's been crazy enough to do this in past but I love animated animal movies so compiled a comprehensive list ,around 250 and excluding insects, correct up to July 2014 in case anyone was interested but didn't know where to look for films about certain animals. I haven't watched all of these and only really terrible ones are excluded, any questions just ask, I've watched quite a few and might be able to help, hope at least one person might find some use for it! Sorry its so long!

Nice list. But I can see you missed out White Fang that had countless adaptations. Also there's a less-known Japanese movie about a wolfdog called King Fang.

Thanks for letting me know, I'll add them onto it.

Oh, also there is an adaptation of Jack London's book, Call Of the Wild. I know only about a Japanese adopatation but I'm sure there were some more.
Anyways, I'll look into that list next time I want to watch a new animated movie xD
