I have a black cat in my neighborhood that has come around for a few months now. I always leave some food out for him. The last couple of days, he has been holding one of his front legs up and won't put any weight on it. Even when he runs, he won't use it. I'd like to take him to the vet to get it checked out, but I can't catch him (even with the bad leg). I've tried sneaking up on him with a large towel while he is eating, hoping to scoop him up into it so he is caught and can't squirm, but he won't go for it. I put some food in the rear of one of the carriers I use for my cats, but he just gives me a look like "Nice try, asshole," and goes on his merry way. Any thoughts on how to best capture the animal safely? I don't want to get bit or scratched to pieces and I also don't want to further injure the animal.
