I have cat, that plays fetch, comes when called, and in general acts like a dog . Oh yeah he eats the dogs food.
I also have a dog, that eats grass constantly but never gets sick, doesn't try and eat the cats food, and generally is very sheep like.
So I went to get a cat and wound up with a dog, I went to get a dog and wound up with a sheep.
Next I'll get a lion that thinks its a turtle, at least that's the pattern I think.
