My cat has been licking his paw since two days and limping as well. We found something black in between his paw but not sure what it is. Can someone help me figure it out?
It looks as if this could be dried blood although it is difficult to diagnose from a photo. I am a human doctor, not a vet and I think that your cat should be seen by a vet as soon as possible.as your cat may have a laceration of the paw.
