The seven month old continental giant rabbit is being looked after at a rescue centre in Scotland.
He's already the size of a small dog but because he's still young he could grow even bigger.
Scottish SPCA centre manager Anna O'Donnell said "He is a very friendly rabbit who loves attention and getting cuddles."

"Atlas is also an inquisitive boy who makes everyone laugh with his mischievous character."
The charity says the new owner will have to have experience of looking after this type of rabbit and lots of space so he can run around.
