I do not understand the spay nueter thingy though.
Ok Let's say you vet charges $75 to spay a kitten. Aunt Jemima wants to buy one of your kittens, instead of charging her for it Aunt Jemima pays the vet $75. So you really won't be getting a payment for the kittens, but technically you are still charging a fee since you are requiring that Aunt Jemima pays for the sir jury before she even gets to take a kitty home. Then when the kitty is old enough Aunt Jemima just has to take the kitty to the vet and since the sir jury was already paid for then she doesn't have to worry about paying for anything else. Does that make better sense?
