A wacky tale of 2 kitties

The makers of a popular kitty litter say a TV-ad campaign by a rival trashing its product is full of it.

In the zaniest cat fight ever, Church & Dwight Co. yesterday slapped The Clorox Co. with a false-advertising suit for claiming felines prefer Clorox’s Fresh Step brand over Arm & Hammer Super Scoop.

The ads show finicky felines rejecting litter boxes filled with Super Scoop in favor of Fresh Step, supposedly because the carbon in Fresh Step “is better at eliminating odors.”

Church & Dwight insists in its legal papers that it has the real scoop.

“Cats do not talk,” according to its legal papers filed in Manhattan federal court.

“It is widely understood in the scientific community that cat perception of malodor is materially different than human perception.”

Church & Dwight also dumps on Clorox’s claim that the ads are “based on lab tests.”

That “supposed substantiation” came from a “severely flawed” study that involved giving eight cats access to only two litter boxes — and weighing the evidence afterward, according to the suit.

“Just as is the case with humans, different cats produce different amount of waste,” Church & Dwight points out.

This raises the possibility that “one or just a few cats” could have skewed the results.

The suit says Church & Dwight also “disproved” the Fresh Step commercials by commissioning an “independent organization” to evaluate the two brands.

Conducted in cat owners’ homes, its test compared how the pets reacted to each litter.

“Of the 158 cats involved . . . only six — or less than 4 percent — rejected their litter box and relieved themselves elsewhere in the home when it was filled with Church & Dwight’s Super Scoop,” the suit says.

“Eight cats — slightly more than 5 percent — rejected their litter box when it was filled with Clorox’s Fresh Step litter.”

Church & Dwight “”‘contends the “false and deceptive” messages in the commercials have caused a “loss of confidence in Super Scoop.”

The suit seeks an injunction against the Fresh Step ads along with “corrective advertising” and unspecified damages.

A Clorox spokeswoman declined to comment.
