Misty and her pal, Sooty play together nicely and he comes indoors for at least 1 meal every day. His owner knows and is ok with it as he is not a well man and often forgets to feed Sooty. Sooty is about 8 yo and was neutered late, about 2 years ago. He seems healthy. His condition has improved since I have been feeding him. He is a ratter, although I'm pretty sure he doesn't eat them, but I have seen him 'playing' with them. When he comes indoors it isn't always to eat. He will lie behind my chair and has his own catnip toys to chew. I gave him his own to stop him stealing Misty's. The thing is, he sometimes hisses at me and I don't know why. The first time was while sitting on the windowsill looking outside. I was going out and didn't want to leave him shut in. So I gently touched his rear hoping it would make him go out. He bit my hand. Just a gentle bite as though to say, 'please don't do that, I don't like it'. Thinking about it after I thought he had probably been looking outside to see if it was safe to go out and I should have realised that and not tried to make him go. Lesson learned. Then he began to occasionally hiss at me. Once, I held my hand out to him while he was behind my chair and he hissed. I realised I was actually blocking his exit, so no wonder he warned me off. Another lesson learned. But most time he hisses is to do with food. I always feed him on the kitchen worktop, well away from Misty's feeding spot in the lounge. When he is eating I can gently stroke his head and back but I never do it for more than a few seconds. I'm just trying to show him I mean no harm. But if I try to pet him before I give him his food, he hisses, even though he knows, when he's in that spot, that food is on its way. If I'm outside and see Sooty I can call him and he'll come for a stroke, pushing his head into my hand. I guess he feels safe on his own territory. Why does he hiss at me? What am I doing wrong? Am I just going to have to accept he will never completely trust me? Sorry for long post it's just I don't know if there's anything I can do to improve things.
