This mutant rat was dispatched in Cornwall earlier this year after being caught nibbling on dog food in a Penryn shed.

Kirstie Rollason tweeted the picture of her 6' 1 tall father in law holding it.

The giant rodent measuring roughly 19 inches from nose to tail was found in the back garden after it had been munching on the family dog’s dry food kept in their shed.

Kirstie said rat was so big the family dog was even scared to approach it.
