For the past week, there has been a cat hanging around our home, in our garden. During the week, I posted about him, as I thought he might be a stray with no home, and I wanted to know what I could do. But, for various reasons, I have concluded he has a home. However, I think he might be hanging around for other reasons. I have stopped feeding him (previously I felt sorry for him, but I do think he has a home, so have stopped). He's very nervous of humans, so I can't get near him, and TBH, I can't tell if he is male or not, I just think he is. I know the following details don't automatically mean he's male, and I could be off the mark, but it makes me think: He seems to have quite large territory. Talking to others to find out more information, he seems to have quite a large roaming area and exhibits similar behaviour with them as well. He seems to only go to homes where there is already a cat/cats. He hung around a lot in the garden, even before I fed him. He is scent marking in the garden (I know this is not exclusively a male thing), and on the door. He is really bothering my young female cat, Holly. But he is not aggressive with her, at all. He makes strange, low meowing sounds, not a growl or hiss. He goes very close to her. She hates him and is very nervous of him. She sometimes goes for him and shouts at him, but he will not retaliate by fighting back (he may bop her, but nothing else), but he will not leave or back away, either. She jumps on the window sill to get away from him, but he still just hangs around near her, a metre away at most. She walks away from him, but he follows her, but not aggressively. He doesn't chase, he just follows her. She is definitely irritated by his unwanted attention. Thankfully, she's still her usual self, and hasn't been showing any signs of stress, and hasn't started to scent mark herself. Holly was a rescue, and they estimated her at two years old. When the rescue found her, they checked to see if she had been neutered, and she does have a neutering scar, which the rescue said was checked by two vets. But they didn't open her up to check. She isn't behaving, and has never behaved like a queen since she arrived at her forever home with us at the beginning of January. But is it possible he might be checking her out? Sorry if it sounds daft, but it's the way he hangs around near her all the time, without being aggressive. Is there anything I can do? I don't suspect there is, TBH! I have stopped feeding him, which I know was the exact excuse he needed to hang around! I don't want him coming in the house when it's summer and having the door open, and he comes in and starts scent marking!! I know the ideal thing would be to keep her in, and I would prefer that, but she loves going out.
