Petco and PetSmart will stop selling cat and dog treats made in China. As of May 1, the FDA has received some 4,800 reports of pet illnesses involving kidney problems, convulsions and gastrointestinal distress.

Sherrod Brown (D-Ohio) grilled officials from the FDA about whether the labeling of so-called “Made in the USA” pet products was accurate.
