Hi,
If your cat has not passed a stool in 24 hours, you can add 2 drops of vegetable oil to his food. If he does not pass a stool in 48 hours, take your kitten to a vet. Never attempt to give a kitten an enema and never give anything like store bought Fleets enema to your kitten. The phosphorus inside is deadly for cats. Your vet can help you with the problem of constipation best, I understand they are expensive but the safety of the kitten out weighs all else.
I would consider a different food for your cat to prevent this from becoming a problem make sure it is high in fiber.
