I'm going to trap a cat tonight that has a broken paw. I've only seen it twice, it lives' in a vacant burnt out apartment. I haven't gotten close enough to see if it's male or female. If it is a female and is nursing babies that would be bad to take the mom away from them. The apartment is not accessible to me, so I would not be able to look for babies. The cat is probably feral or just very scared. Someone may have broken it's paw on purpose. I saw another one with a broken paw in the same complex, people here are very cruel to animals. Have you ever tried to take a cat out of a trap and handle it in order to see if it is nursing kittens?
