my 9 year old cat waffles sprained/strained his right back leg while running, I took him to the vet they took xrays, and after 3 vets reveiwed them and $200 later they found nothing. they gave him some pain medications and thats about it. This happened about 1 1/2 weeks ago and still seems to be no better he does not put any weight at all on it and justs lays around all day. Does anyone have any suggestion? please help!
