My parents brought their 80 pound lab to our house the other day. My orange cat locked onto that dog and decided it was on. He ran around behind her jumped up on her hindquarters and the fur started to fly. Now their dog afraid of cats and if you start breathing like panting dog in my house. My orange cat comes into the room looking to kick some ass. He is not very big. Probably 7-8 years old 10 pound neutered male. He was a dirty alley cat before he became a house cat due to a new cat poinsiong neighbor that killed my other cats.
