For months we thought this cat was a stray (very skinny and very old). It turns out he does have a loving owner who cares very much about him, and took him to the vet when we commented on how skinny he looks. The owner isnt home for most of the day so the cat is constantly crying outside our house and getting inside uninvited. He even scratches the door and knocks on the windows!! The problem is we have a terrier who is scared of cats and were scared he will bite the cat out of fear. But the cat is completely unconcerned about the dog!! How do we keep the cat away from our house? We have stopped feeding him for a start.
