We live in a nice area for cats and our two cats go outdoors whenever they please and they love it, it is a safe area generally, no cars around, lots of grass and trees etc., no wild animals. A few months ago a new cat turned up in the area, beautiful grey thing, looks very well cared for, groomed, fed etc. however HE has obviously not been neutered. To cut a long story short, he has been harrassing every local cat and has clawed two (one of whch was ours), both ended up in the vets with abcesses - which were small as we are vigilant owners. We don't know who owns the cat, they are obviously incredibly selfish, we have heard it mating a few times so that's going to be another 10 unwanted kittens probably. Our cats (females) are both spayed as are all the local cats. The problem is how to stop this new cat from attacking our cats, we haven't seen him in about a month now so maybe he is gone, who knows but is there anything obvious that we can do to stop him? The vet reckons it is a territory thing and as such our cats have to defend their own territory and we cannot do that for them but any suggestions welcome
