I love my dog or cat, and want to have puppies just like her.

A dog or cat may be a great pet, but that doesn't always mean her offspring will be an exact copy. Professional breeders who follow generations of bloodlines can't guarantee they will get just what they want out of a particular litter. A pet owner's chances are even slimmer. In fact, it is very possible that an entire litter of puppies or kittens might receive all of a pet's (and her mate's) worst characteristics.
