My 4 year old cat who has been neutered years ago is getting into fights with a cat that is new to the scene. This other cat is very aggressive and has been urinating all over our garden. I've also seen it attack other cats. My poor cat is covered in deep scratches and traumatised after each fight.
I am worried he is going to get really hurt. The gardens all back onto each other but it is very difficult to find out where the other cat lives. Ideas on how to manage this please??
