How do I have my friend’s baby kitten go #2?

Is the kitten separated from the mother? The mother cat helps her kittens \\\”learn\\\” how to defecate by licking them. You can mimic this:

(from http://www.feralcat.com/raising.html)
The kitten\\\’s natural mother takes care of both ends of her baby. By licking the kitten\\\’s abdomen, she stimulates the bowels and bladder and tidies up the resulting mess. A surrogate cat mom should gently rub the kitten\\\’s abdomen and bottom with a cotton ball or pad or tissues moistened with warm water. This stimulates the discharge of waste and keeps babies clean. Be careful to rub only enough to get them to expel waste materials. Keep the area clean and watch for chafing which might indicate that you are rubbing too hard or not cleaning well enough.

well i guess u just have to try to give it like maybe food that helps it go #2 but just keep it drinking liquades i heard that milk isn\\\’t good for kittens.

milk isnt good for kittens (or so i have head) and maybe some laxitives from the vet could help
