IMO this is what a repetable breeder is:
1. One who has been breeding for years and knows the inside and outside of their particular breeds - this includes history, some genetics, pedigrees, good points/bad points, personality of the cat, possible genetics problems, and shows their cats.
2. One who has "proven" their cats in a show ring with champions AND grand champions in their breeding program. This means they know the quality of the cat and they are working on improving the lines - not just breeding for the sake of breeding a purebred cat. Champion is easy to obtain - you want to see GRAND champions in the lines.
3. One that keeps the kittens till they are 12-16 weeks old and gives them the first and 2nd series of shots. They keep them this long to evaluate them as to pet or show type and to socialize them properly.
4. One that has no problem of letting you see how their other cats live. Watch for cleanliness and health of the adult cats. Are they kept in tiny cages or do they have reasonable run of the house. If you walk into the house can you tell there are cats in there - smell, etc.
5. You should expect a healthy kitten - clean ears, eyes, no sneezing, clean fur, etc.
When you put a deposit on the kitten, the breeder usually keeps you informed of their progress. Ask for a few pictures (if possible) of your kitten growing up (like 1 month old, 2 months old, etc.) Ask to see the pedigree of the parents.
After you get the kitten, take him/her to your vet within 48-72 hrs and verify a clean bill of health. The breeder should have you sign a written contract on the health of the kitten, your responsibilities in spaying/neutering. Also what happens if you can't keep the kitten or there is a genetic problem in the first year?
Most times you won't get the registration until you have the kitten neutered/spayed. If the kitten is done (early) then you should have those papers when you pick up the kitten. A good breeder has registration done within a month after the kittens are born and should have all paperwork back in a few weeks from the association(s). IMO there is really no excuse not to have paperwork done within a few months of the litter being born.
Go with your gut feeling - if you dont' like the person or the way the cats are treated, do NOT buy from this person - don't feel sorry for the animals and buy anyway; that only encourages a bad breeder to keep breeding.
Go to cat shows and talk to more then one breeder and do NOT buy the first kitten you see. Most good breeders will have a waiting list for kittens - so be patient. Don't settle for one kitten; wait till the right kitten is born for you.
Make a list of exactly the type, color, sex you want and stick to it
