I'm very sorry about JoJo! In the meantime, buy the smallest human baby diapers you can find (pet diapers cost much more)!!! Cut a small hole in one side for his tail to poke through. In his case, you may not need to even do that though. Just be sure to check his diaper several times per day and wipe him with a baby wipe to get the urine and / or feces off of his skin. If urine builds up on his skin for too long, he will get burns. I know because I am doing this with my poodle. She jumped off our bed and injured her spinal cord. After surgery and $3,0000.00 later, she still is paralyzed and incontinent. I wish you the best of luck with your kitten!
