The ongoing controversy over tainted pet food continues to spawn new products. The latest being marketed out of Georgetown, Texas, is VitaPaw, “a vitamin-enhanced water for cats and dogs,” according to a release. And who would buy such a product? “Not everyone feeds the highest quality pet foods, because of cost or habit, and a good vitamin supplement can add the missing nutrition,” said a company rep. Which begs the obvious question: If people are buying their pets cheap food, what makes anyone think they’ll spring for expensive water? Make up your own mind; the stuff is available at the VitaPaw Web site, at $1.50 a half-liter or $2.25 for a liter bottle. Tap water is still basically free.
