A cat called Stewie is hoping to claw his way into the record books.
He measures 1.2m from nose to tail, making him the world's longest domestic feline.
The five-year-old Maine Coon cat, from the American state of Nevada, measures precisely 123.5cm.
Maine Coons are a breed of cat that seem to do well with this record - the current holder is also a Maine Coon, but it's two centimetres shorter!
