Ten-day-old kittens are not yet fully developed, and their excretory system may not be fully established. Generally, newborn kittens cannot defecate on their own and rely on their mother's licking to stimulate excretion.

If kittens are not cared for by their mother, or if the mother is unwilling or unable to care for them, then it is necessary to artificially stimulate the kittens' anus to help them defecate.
