The best performance by a cat in a TV commercial this week goes to the fluffy mess in this new British spot for eyewear maker Specsavers. Not that the veterinarian here would know—he's not clear on what a cat is anymore. Specsavers, of course, has a long and proud history of offbeat commercials. The best mistaken-animal-identity spot, though, remains the brilliant raccoon commercial from Sears Optical.
