Bumper likes to bite his paws and the bleed and don't heal very well. My vet recommended wrapping the paws with normal moisturising lotion (or using baby booties) just to stop the cat eating the lotion.
Unless you can rub the lotion in well enough first. Also try to move/cover anything that they can cut their paws on. Bumps, for instance ould get itchy paws and would rub them on the heating vents in the floors - making his paws worse, we covered them and he couldn't get to them which helped a lot.
