Hissing Sid

This is one of the most unfriendly cats I’ve ever met. As soon as I go near him he hisses although he is quite happy to eat a bit of chicken now and then! I don’t know where he comes from and he seems far too well cared for to be a stray. He turned up for a couple of months last year and then disappeared. A month ago he reappeared and is often on the window sill when I come down in the morning. He’s a handsome cat and I just wish that he was more friendly.
