i'm so happy to read this and then to find out that boo is doing much better.

we picked up a cat at a no kill shelter that was run over and it was laying on the side of the road (the person said who brought him in).
well his hind legs were real bad and bandaged up.the helpers changed his dressings daily for weeks i was told, and there were huge scrapes all over his neck and other areas.scars now.
but we've had him a year now and his hind legs will never be like a normal cat.he has a hard time jumping up on things but manages usually.he's a good boy...all black (real black everywhere).he was listed as 3 yrs old but our vet said he was in his more in his senior yrs.(we agreed)
but he's doing great.

maybe boo will be ok like our Kevin.I hope boo will feel better soon.
