I am really distressed right now, the irresponsible cat owner at the back of me is not home and a passing motorist made us aware one of her cats, young one has been probably hit by a car,(not him as it ran into our property he thought it belonged to us, I don't know what to do , there are so many places it can hide, we had a look and could not find it , then as I had written a note to this woman and was about to go over and leave it on her doorstep I spotted the cat under my sons car, it has a very badly hurt hind leg, bleeding and looking so painful, I felt sick in the stomach just seeing it suffer so much, it is feral because she has not handled the cat since it was a kitten, we almost had it cornered but it outsmarted us, now I know it is out there suffering and I just feel so bad, i cannot see us getting the chance to catch it again,poor thing it looks bad, please give me any ideas or advice, if i can get it we will be taking it straight away to the vet, this woman probably won't even bother and believe me it needs medical attention soon.

Please help I feel helpless.
