World's cleverest cat, destroys automatic pet feeder in seconds.

This video was made in the 1980's when Propeller our pet feline very skilfully found a way of opening an automatic cat feeding device manufactured by Pet Mate. The video was sent to Pet Mate at that time and they suggested the device was either faulty or the cat was quite exceptional. A replacement feeder was obtained and suffered the same fate. Maybe the company at the time should have employed Propeller as part of their destructive testing team?
