i only have 1 brave cat who suffered most of her life so she is tough and she is like ninja cat when the dog was asleep she jumped over the fence and smelled the dog and smelled around the room and even went by the window and the dog didnt even know she was around but when the dog starts barking she is gone and her tail gets really fat and she goes into combat mode i know the cat will go by the dog if it doesnt bark this cat used to be best friends with my love birds once that one cat goes the next 2 house cats (scared ones) who dont know what a dog is might follow
