Timmy the cat has grown so big he has to sleep in a kennel at night!
The black and white pussy only eats a can of cat food a day but still weighs a whopping 10kg (22lb) - which is about the same as a two-year-old child.
It's thought Timmy, who was adopted from an animal shelter, has always been large and is simply "big-boned".
His owner Sean Langley said it was hard for Timmy to make friends: "He doesn't have any other animal friends - I think they're scared of him."
Luckily for Timmy he gets loads of care and attention from his loving family instead!
