I've never see a dog kick a cat's ass.........In fact, I can only think of 2 times I've seen a dog/cat fight, and the cat won both.......The cat stole on the poor dog a few times and locked on his hind leg and then the cat dipped. The dog was never gonna catch it.......This was against a pit.......The other time, a cat scratched the fuck out of the dog a few times and the dog ran like a bitch........This was some kind of hound.
My point is I always think that dogs fuck up cats due to most cats (cartoons I guess) always seem to be afraid of dogs.......But that's bullshit.
Also contrary is the majority of the time when I see cats and dogs together, they are cool......Or completely ignore each other.
Cats and dogs DO hate birds though. Wing envy.
