Also, even though I realize that in time he can become a lot more comfortable around humans, he is never going to become an adorable lap-cat, is he? There's only so far that he can be domesticated, right?
Update, a month later: He has become an adorable lap-cat!
Seriously, who knew cats could be so nice?!!? He rubs himself against my ankles when I walk through the room, and spoons my leg when I'm laying on the sofa. And he never minds being picked up.
I obviously didn't know much about cats, because he's become so different to how he was at first. I guess what I describe at the start of this thread is a cat in shock, and he's now settled in.
I've bought a cat-friendly laser pointer, and a big tub of catnip.
We leave the window open a lot so he can come and go as he pleases. It's fun to see him climbing in the tree, walking on the roof of the conservatory, or peaking at me through a hole in the neighbour's garden fence.
One morning he brought in a toad, which was injured but still able to hop around. He was chasing after the poor thing. It was horrible! Perhaps we shouldn't leave the window open at night if we don't want him to bring us gifts?
Also, the guy in the flat upstairs has a huge tabby cat which accesses the garden through the first-floor window overlooking the conservatory. This cat has come in through our window a few times, and I don't think our cat likes it much. Should I shoo this cat away if he comes in again? They are both sharing the garden so I think they had better get used to each other, but this cat coming inside our flat is maybe a bit much from our cat's perspective.
