Sorry if this isn't the correct place to post this. I have 2 cats of my own and like them to be free to come and go as they please. Therefore we fitted a catflap to our front door, it is always left open. However a cat keeps coming into the house, it sprays all over the place and eats all my cats food. How do I stop this without having to lock my cats inside the house, I have a young baby in the house and don't like the idea that this stray could be spraying on her pram etc. Likewise I don't want a catbox in the house. Any advice would be appreciated.
