I’m a dog person really and know very little about cats. However, my step-daughter has a cat, which had been living at her Dad’s until last year and now lives with us. The cat spends quite a lot of time outside and no doubt prowls the neighbourhood. In the last couple of months I have noticed that we seem to be getting a collection of cats in the garden, with at least three regular visitors, often camping out in our garden, not just passing through. One of them has tried to get in the house. Is this normal? It’s always the same cats, a small grey expensive looking thing, a tabby and a big brown beast of a cat.
