Kittens are born completely dependent, so for the first few weeks of their lives, a mother cat has to stimulate bladder and bowel movements by washing the area underneath the kitten's tail.

When they are born, and they never need help. If your cat is having kittens it is important to keep the kitty shelter clean. Many times mommy kitten will take care of the kittens themselves, but the bedding will be nasty if it is not kept clean. Yes you can move the kittens, if you are scared of hurting the kittens by handling them slide a washcloth under them and lift them out of the bedding that way to clean it or change it.
Puppies already know how to poop. Edit: The original answer is incorrect. Puppies need stimulation to poop and urinate when they are first born. Typically the mother will lick the puppy to get it to urinate or poop, but if the owner needs to assist then you can use a warm paper towel on their stomach and anus to get them to use the bathroom. This is very important until they can do it on their own, which is about 2 weeks after birth typically.

This really depends on their diet, or whether they are of an age where they will start to spray (usually 4 to 6 months old). Usual urination should not smell, but a cat's spray smells incredibly strong in order to let other cats know of the owner's territory, health and sexual information. Kittens should be neutered and spayed before 6 months old, before they start to spray.
