Depending upon how old they are, try putting an ad in the newspaper. Do NOT say "free to good home" however, because you will get calls from Laboratories who are looking for free cats and kittens. Ask for an adoption fee, say $50-75. It sounds a little high, but it will weed out the undesireables and will also guarantee a home that is able to care for the cat properly, i.e., medical, all the immenities,etc.

Also, put up signs in vet offices and pet stores. Again, do not give out the kittens for free. Charge an adoption fee. Whatever it costs you to have the cat tested for Feline Leukemia, Feline Aids, and spayed/neutered, providing you have done so. When a prospective adoptee comes along, show them the vet bill. Let them know that you have saved them alot of time and energy by having all this stuff done. Laboratoeis will not pay for cats/kittens.

Good luck in finding furrrrever homes for the kittens.
