A PetSmart spokesman Bruce Richardson said the company does extensive testing on toys they sell in the store.
Richardson stated, “We have a technical services group, which is headed by a Ph.D., and includes veterinarians and analysts who manage the quality. They keep close to these issues.”
PetSmart also has an independent company to conduct quality-assurance tests on toys, including tests for arsenic, barium, cadmium, chromium, lead, mercury, and selenium. They said the same standards for human safety are used for the testing of pet toys.
