Breeding domesticated animals can be quite complicated.  There are sites on the web that will help you find a breeder for this process.  It is very complicated to breed animals.  You may want to have pure-bred animals to mate for a strong pure line that will be healthy and live a long time.  You may want to cross-breed more than one type of animal, and this takes research to make sure that your results are good for your needs and for the animal’s health and well being.  If you wish to do the breeding of your animals yourself, do the research.  Get opinions from qualified breeders or veterinarians.  There is a lot to know, and the information is available, in books, on line, and even your local newspaper will have ads about breeders in your area.
