First, let me commend both Cassie and Buttercup for their wonderful taste in cats! *grin* I just love the Siamese cats!! They are among my favorites, so if I can be of any assistance to you, I am happy to be.
When choosing a breeder, the first thing to consider is whether you want the old-style body type or the show-style body type. Not many breeders will have kittens in both body types, even if some of the show-style kittens are more round and moderate in appearance, they are still show-style kitties. If you are interested in the old-style Siamese cats, I might suggest to visit PREOSSIA's web site, and look into obtaining your cat from one of the many reputable breeders there. It is a wonderful organization devoted to the preservation of the old-style Siamese cats, and really deserves the support. Visit them at http://www.oldstylesiamese.com
If you are interested in a show-style cat, visit The Fancier's Breed Referral List and locate a breeder in your area there. Visit them at http://www.breedlist.com.
This is a wonderful resource of breeders from all over and would be my first stop. (They also have a listing of Old-Style breeders there, under Traditional Siamese.)
Once you've narrowed the list down to a few breeders that you want to contact personally, then the fun really begins! You'll want to make certain that ethical breeding practices are being followed, and you will be interviewed by the breeder. Some things to consider when choosing a breeder are:
Make certain the breeder does not sell kittens before a minimum age of 3 months AND 2 pounds in weight. Siamese kittens do not physically mature early, and their immune systems are not fully developed until a year of age.
Make sure the breeder does not sell kittens without a contract which very specifically details what the breeder expects of the buyer, and what the buyer should expect from the breeder. There should be a Take-Back Clause in the contract - No Siamese kitten from an ethical breeder should EVER end up in a shelter -- the kitten/cat should ALWAYS be welcomed back by the breeder.
Make sure the breeder does NOT sell kittens without vaccinations and a written form of health guarantee, or allow a kitten to leave at 12 or 16 weeks if it is not well or the breeder has any concerns about it at that time. In addition, many breeders, if asked, at mostly at an additional expense, will provide a certificate that the kitten has been tested for FeLV and is negative.
Make certain the breeder is always available to answer questions and assist you as the new owner whenever possible.
During the interview process, the breeder should carefully screens potential buyers, and will refuse to sell a kitten to an inappropriate buyer. Not everyone understands the special traits and personalities of the Siamese breed, and an ethical breeder will explain the breed's quirks to a potential buyer so that this person fully understands what the breed is like and what to expect. If the Siamese personality and activity level is NOT what the potential owner wants, it is important to weed these people out during the screening process. More people are screened out than ever get to buy a kitten.
The ethical breeder should sell pet quality kittens with a neuter/spay contract or sell these kittens already neutered or spayed, a practice which is becoming common in areas where the vets are progressive enough to practice early neutering/spaying. In no event, should a pet-quality kitten be sold with breeding rights, nor should an ethical breeder sell a breeding-quality animal to someone who does not follow the same ethical guidelines on breeding that this breeder practices. You will NEVER see an ad from an ethical breeder which states "Siamese kittens - $200 without papers, $300 with papers".
The breeder will, in the screening process, ask a potential owner personal questions such as:
Do you own your house or rent; and if you rent, they may require a statement from the landlord that animals are permissible.
If you currently own animals, who do you use as a vet and what is his phone number? Be prepared and let the vet know in advance that they may have to issue either a verbal or written statement of your past history in caring for pets to this breeder. It will save a lot of time, trouble and effort on your part to get your vet's agreement to do this BEFORE you start calling on breeders.
Have you owned this breed before; if not, do you understand their temperament and needs?
If you have other cats, are they allowed outdoors?
Are those cats declawed?
Do you have very young children in your house?
Do you intend to breed?
What would you do if you had to move - look for a place which allows animals or give up the cat?
These are only a few of the issues to be addressed, but enough for now. When you get a little closer in your search, let me know if I can help you further.
Best of luck,
