Just thought I'd let you know we're keeping the stray kitty !
None of the rescue places in my area were willing to take him on, I guess they're full at the moment with kittens.
They did suggest I rehome him myself but to be honest I have no experience of that kind of thing and he's still a bit frightened so not sure how he'd react with kids or a noisy household.
So he's staying with us as an outside cat and will move with me next year.
I feel bad leaving him outdoors but I bought him a house today and he's well fed so hopefully he'll be fine for the winter !
