42. RB : Requires the buyer to spay/neuter pet-quality kittens
BYB : Encourages buyers to breed, regardless of quality


this one really a good one because some "domestic breeder" here doesnt even concern themselves with neutering and spaying when they advertise here.

btw, a really thourough checklist for anyone who is inspire to be an ethical breeder.
