I got my new cat (she is only about 1 year old) from a rescue center about 6 weeks ago. I live in a small terrace house with a magnetic cat flap in the back door. I have just managed to get her to start using the cat flap and using the garden rather than a litter tray. She was really happy and content until about 10 days go when a very large white Tom cat (I think he is a stray) came right into the house and started fighting with her. I've tried all the usual ways of getting rid of him but he still comes in at about 6.30 every morning and fights her. She is half his size and is now quite scared of him and he comes and lies now on the kitchen tops! I'm at a loss of what to do other than get a very expensive catflap, which I'd like to avoid if I can. He isn't overly scared of me, I've tried spraying water, shouting, clapping and running after him...can anyone suggest anything else that might get rid of him for good? My little kitty was doing so well and now she really needs my help to get this bully out of the house! Thanks x
