If a mother cat is present, the mother cat will lick the kittens' anuses to stimulate their defecation. If the owner does not see the kitten’s excrement, it is normal because it has been swallowed by the female cat. If there is no female cat and manual intervention is needed for the kitten to defecate, the owner can wet the kitten with sterile gauze and then wipe the kitten's anus to stimulate the anus to urinate.

When the owner or the mother cat stimulates the kitten, the kitten will excrete yellow stool. After expelling, the cat's anus needs to be cleaned to keep it dry. Under normal circumstances, kittens will excrete yellow stool every day, but this does not happen every time the kitten is stimulated.

Kittens will start to learn to urinate and defecate on cat litter after about one month old. Owners can choose to use small boxes to train kittens to use cat litter. For cat litter boxes, you can choose a shallower box to make it easier for kittens to use. In addition, if the kitten does not excrete in the litter box, you can put the kitten in the litter box after the kitten has eaten to let the kitten get used to the litter.
