For newborn kittens, the mother cat will lick the kitten’s reproductive organs with her tongue to stimulate it to urinate and defecate. If there is no mother cat, the owner needs to use a moist paper towel to gently wipe the cat's reproductive organs to stimulate the cat to urinate. Generally, every time you feed a kitten, you need to help it eliminate milk.

After a kitten reaches one month old, it will start to urinate on its own. The owner should prepare a litter box and cat litter, and put a little cat excrement on the cat litter to attract the cat to the right place to excrete. The owner can hold the cat's paws, dig into the litter and bury it, and teach the cat how to do it.
