NEW YORK -- A New York federal judge says the Clorox Pet Products Co. must stop airing a cat litter commercial that unfairly seeks supremacy over a competitor.
The Clorox ad was aimed at Church & Dwight Co. Inc.'s Arm & Hammer brands of cat litter. It claimed a smell test involving a jar proves Clorox's Fresh Step cat litter outperforms Church & Dwight's products.
The judge found it "highly implausible" 11 panelists would "stick their noses in jars of excrement and report 44 independent times that they smelled nothing unpleasant." He found the claims "literally false."
Oakland, Calif.-based Clorox says it's disappointed in Tuesday's ruling. It says it defends the ad's truthfulness.
A message left Wednesday with a lawyer for Princeton, N.J.-based Church & Dwight hasn't been returned.
