My character "Mutt" is a husky/coyote mix, and she is a bit of a glutton and not picky. In a pinch she'll eat carrion because like cheese, the stinker food is, the better it tastes.
My fursona usually has a pencil in his pocket.
Tangentially related: I think it's relatively uncommon that my characters/fursonas(fursonai?) are amoral/nihilistic anti-heroes. Most furry characters I find are either average joes or some sort of hero. Most "villian" characters have to do with a fetish... which is kind of sad.
Mine though reside in that moral blind spot people have for characters like GTA protagonists and Hannibal Ecter, where it's OK to be completely amoral as long as you do it with enough class and enthusiasm (and towards 'good' characters that are cartoonish and unlikable) They depend on the conceit that, yes, they are bad, but they're more fun to watch than people who are good. Basically their philosophy.
