Four rare Bengal kittens are expected to sell for up to £80,000 each.
The cats have a Bengal Cat for a mother and an Asian Leopard Cat as a dad, which makes them one step away from being wild, and very rare.
Bengal kittens that are several generations from being wild normally sell for hundreds of pounds each.
The seven-week-old kittens' dad, Apollo, is one of only five leopard cats in the world which can breed to make Bengal cats.
Although Apollo is officially wild, his owners describe him as "about as dangerous as a frozen chicken".
He lives in a room in their house, and eats a whole chicken and 200g of steak a day.
Frankie and Pauline Turnock, from Aberdeenshire, plan to sell the three female kittens to a breeder and sell the male as a pet.
