My pit Herman won’t tolerate cats. He has gone after cats at Chuck & Don’s pet food store and the manager once had to block him as I pulled him away from the cats. I don’t trust him with cats Period. Herman is still welcome there, and it’s been made clear that he is not a “bad dog”, he is just a dog who hates cats. Part of that is probably genetic, as I’ve been told by the manager at Chuck & Don’s that cats are sometimes used as bait animals in dog fight training. Still, Herman is loved and accepted there. The staff come out with treats for Herman and love on him every time we go. Animal aggression is a problem with Herman, and we have taken steps to address this.
