In a statement provided to The Dodo, PetSmart said that "nothing is more important to us than the health and safety of pets."
"We take these allegations very seriously," the company said. "We hold ourselves and all of our pet suppliers to the highest standards. We are reviewing the matter internally, and if we find that our standards have not been met, we will take appropriate action immediately."
