The pet food company MenuFoods knew its product was deadly

Because they had tested it in house and more than six... SIX... cats had died. But they sent it out anyway.

(CBS/AP) As many as one in six animals died in tests of suspect dog and cat food by the manufacturer last month after complaints the products were poisoning pets around the country, the government said Monday.

"That's a huge number, considering when you feed pet food no animal should die," says CBS News The Early Show veterinarian Dr. Debbye Turner.

That's about this many....

And they sent it out anyway. Class action suit, anyone?

Update, Canadian firm, U.S. plants:

Agency investigators are looking at other ingredients as well. The wet-style pet food was made by Menu Foods, an Ontario, Canada-based company. The FDA on Monday had investigators at Menu plants in Emporia, Kan., and Pennsauken, N.J.

Menu Foods told the FDA it received the first complaints of kidney failure and deaths among cats and dogs from pet owners on Feb. 20. It began new tests on Feb. 27.

Update: It is rat poison used on the wheat sent from China.
