One of the common complaints of the 88.3 million cat owners in the United States – 60 percent of them, according to the 2008 National Pet Owners Survey -- is odor. In response to this complaint, Arm & Hammer, a division of Princeton, N.J.-based Church & Dwight is bringing two new products to market that aim to fight this annoying problem. The first is a new Clumping Cat Litter with Ammonia Block Formula, which destroys ammonia odors on contact. The Cat Litter Deodorizer Spray also targets the odor, but is recommended to be used daily. The litter retails for a suggested $6 to $12, depending on size, and the spray goes for a suggested $3.49. Get more information by visiting www.armandhammer.com.
