How much Should I Sell my Kittens for?

Well, first off, make sure they are healthy before you give them away. Make sure the people you are selling/giving the kittens/cats are responsible, and i think you should sell them for $0.50 + how much it cost for spayed/neutered. Please, I repeat! PLEASE give them to responsible people! I don't want anyone harming the cat/kittens. I love animals
