World's fattest moggieWednesday, May 9, 2007
Meet Orange Thing -- OT to his friends.
The ginger moggie is the fattest cat ever recorded by Guinness World Records.
He weighted in at 40.9lb (18.6kg) by Guinness World Records before the body stopped recording animal weights in 1998 through fear their owners were purposely fattening them to unhealthy levels.

He is so over weight he has to stop to catch his breath at the top of the stairs, pretending his is just stopping to clean himself to save his dignity.

Guinnes World Record Fat Cat

But he is not the fattest cat ever 'unofficially' recorded.
Last year a seven-year-old cat from Bournemouth called Honey tipped the scales at 19kg.
There have even been reports of a 38kg feline from Minnesota, USA.
