Prospective owners should be knowledgeable and nurturing, never adopting a kitten on a whim, solely for their children or as a present for someone else. Go through the guidelines of responsible pet ownership with them and feel free to refuse anyone you feel will not offer the kitten a good home. Asking for payment to offset your vet costs will help rule out people who aren't serious. Sound them out about whether they will get the kitten sterilized; if not, you are ultimately responsible for adding to the cat overpopulation problem. There is no guarantee, however, that even an apparently ideal adopter will keep the kitten for its entire life and give it nothing but the best care. You owe it to each kitten to be willing to take it back at any point in its life if things don't work out, and keep it yourself or find it another home.
