dude, you don't sell kittens. You give them away or give them to a shelter that will adopt them out. They should be spayed or neutered before going to a new home. PM koolaid, she can give you a ton of info.
With the extreme amount of cats and kittens looking for good homes, selling kittens rather rare. That does not mean that you are wrong here Keith, but rather perhaps not aware of how many cats are euthanized or live on the streets because homes cannot be found.
I cannot tell you what to do, that's not my job here. I just hope that you can find these kittens good homes, regardless of monetary compensation.
One female cat can be responsible for over 480,000 cats in seven years. Low cost spay/neuter programs are available at PAWS Chicago. If someone brings one of these cats into their home before they are tested they chance bringing in some serious problems to their existing pets. These kittens have not been tested for FIV, Feline Lukemia, or FIP (which is difficult to test). Fe Luk is transfered by saliva, and can be deadly to other cats in the house. These cats have also not been de-wormed. Many parasites can be transferred to humans, including round worm, and ring worm. When purchasing a cat from a shelter the fee includes the spay/neuter, de-worming, testing, flea treatment, and vaccinations. Here are some helpful links for bringing a new kitten home:
I should have added that I have personally ordered products from the two pet med sites that I posted, and have had no problems with them (huge savings!!!!). The products are shipped from Australia and are the real deal! I would tell anyone to order Revolution flea treatment over Frontline (or any other). Revolution is the only flea treatment that also helps prevent heartworm and a multitude of other parasites including roundworm. Frontline is ONLY a flea treatment.
FYI - Heartworm is now a very big problem in cats; not just dogs anymore. Heartworm is transmitted by mosquitoes! Another bad one is a tapeworm; they get these by just eating a flea.
