(I thought you were looking for teal eyes? The ones you just bought were aqua, or I'd have offered them to you first, are you just looking for any in that color range?)
Giraffes are pretty fascinating! I haven't spent much time with any of them though.
Rabbits, huh? What kind of rabbits? All of them? I admit to a huge weakness for the super-soft-long-furred brown ones with floppy ears of any specific variety, although a neighbor once had a white one with black spots of some breed or another (she told me many times but I always forget two minutes later) and he was a really funny character, she'd managed to "train" him somewhat (or at least discovered repeatable behaviors that she could deliberately trigger, lol) and so he was fun too....
I don't really have a favorite so much. I like the idea of a lot of animals that I wouldn't want to spend a lot of time around, and the look of others that might or might not fall into either of those first categories, and....
well.
There's always the "look at the cute thing right in front of me this very moment" syndrome.
So I tend to say my "favorite" is whichever I spent time with last, or saw a picture of recently, or just finished reading about, or similar.
It's a weakness.
(Like I was just tempted to say "wombats!" because I was reading
"Digger", a webcomic about a wombat and wombats are now on my mind)
