Premium Edge Cat Food, manufactured by Diamond Pet Food, was recalled in September, but more information was made available today regarding the problem with the cat food.

WASHINGTON — A Missouri company said Tuesday its recalled dried cat food has sickened 21 cats and the pet food was distributed in multiple states in the South and along the East Coast.

Diamond Pet Foods recalled certain bags of Premium Edge Finicky Adult Cat and Premium Edge Hairball cat food in September because they could lead to gastrointestinal or neurological problems for cats. They do not contain enough thiamine, an essential nutrient for cats.

If cats fed these foods have no other source of nutrition, they could develop thiamine deficiency. If untreated, this disorder could result in death, said the Meta, Mo., manufacturer.

The company updated information on the recall on Tuesday, saying it has confirmed 21 reports of thiamine deficiency in New York and Pennsylvania and the pet food was distributed in 18 states altogether. These states include Maine, New Hampshire, Vermont, Massachusetts, Connecticut, Rhode Island, New Jersey, Maryland, Delaware, New York, Pennsylvania, Virginia, Alabama, Tennessee, North Carolina, South Carolina, Georgia and Florida.

For a full refund, consumers can return the recalled cat food to the place it was purchased. For more information, consumers can call 800-977-8797.
