She should still have the original pink slip that was given to her when she bought the kitten if it was bought as a registered kit. If she has that it will have registration number on and all the details. She then needs to complete the blue transfer slip to pass over the kit to you. I have a supply of the blue forms if you want one posting out. I would certainly not buy the kit without seeing her original pink slip and her also her completing and signing the blue slip.
