Most kitty litters consist of small, absorbent particles which can become stuck to your cat's paws fairly easily. Kitty litter can cause health problems if your cat ingests a significant amount of it while he is grooming himself, so it is better for your cat if you remove the kitty litter from his paws for him. Switching litters can help cut down on or eliminate this problem. Try using different types of kitty litters to see what litter works best for your cat without getting stuck to him.
Restrain your cat by wrapping him snugly in the bath towel with all four feet tucked inside. Leave his head and tail loose. Use clips to fasten the bath towel closed. Have your helper hold onto your restrained cat to soothe him and keep him in place while you work.
Extract one paw at a time from inside the towel by pulling it out through the nearest opening. Gently brush as much of the trapped litter loose from his paws using your fingers. Depending on the type of litter that is stuck in his feet, most of it will likely come free with just a little bit of effort.
Wipe the paw down with a damp washcloth. Kitty litter that is stuck in between the paws should dissolve relatively quickly once water is applied. Apply as much water as necessary to dissolve the litter and then wipe any remaining debris away.
Take your cat to the veterinarian if you cannot get the litter loose from his paws. If litter is seriously embedded, it can cause your cat significant discomfort.
