Kitty is going to the vet in two weeks to follow up on his uti but I need to know if this is something that needs to be addressed sooner. He doesn't use the litter box, he goes on pee pads. I just noticed his paws being in such bad shape when I saw tiny spots of blood on my bed where he sleeps. No puss as far as I know/have seen. I'm attaching two pics, one of his left rear paw and one of his front right paw. Any ideas??
