CBS News reports this afternoon that Canadian pet food manufacturer Menu Foods knew that their pet food was killing cats and dogs by February 20th but did nothing to save the animals that are now dying. Menu Foods definitely knew what they were doing and made a conscious decision to sell tainted pet foods to American pet owners. The company claims that only one dog has died while New Jersey alone has had more dog deaths than that and Menu Foods is known to have killed several of their own test dogs with it almost a month ago.
