Our Golden/Lab mix has play dates with our friend’s pit bull terrier mix all the time and it is one of the most affectionate dogs I have ever known.
She (the pit bull mix) is an attention-hog, loves to be petted, listens well to commands, and will make you wet with drool because it wants to lick you all the time. Then, it wants to lay in your lap and get its belly rubbed.
Just because a dog may be a pit bull or has pit bull blood, doesn’t automatically make it a killer.
Visiting YouTube and searching for both cat and pitbull will turn up a nice group of excruciatingly cute videos where the pitbull and the cat are snuggling and playing together to music.
