Cats usually have very few problems giving birth.  If you are breeding your cat you want to insure a smooth pregnancy and delivery. A checkup before breeding will make sure that your cat is healthy and ready to carry her litter for the nine week term. A follow up exam and ultra sound at four weeks will allow your veterinarian to determine the number of kittens.  If the litter is small, this could mean larger kittens and possible delivery problems.  Before your cat is ready to deliver, prepare a cat bed or a box in an out of the way place such as a closet.  The spot should be quiet, warm and secure for your cat and kittens. After she gives birth, watch and make sure that the kittens bond properly.
