The Wellness Pet Company has issued a voluntary recall of certain lots of their canned cat food due to less than adequate levels of Vitamin B1 (Thiamine).

WellPet has recalled some of its Wellness canned cat food after finding less than adequate levels of thiamine.

Cats fed only the affected brands for several weeks may be at risk of developing thiamine deficiency, the Monterey County Health Department said Friday.

The products affected in the recall are all Wellness canned cat food with best by dates from April 14, 2013, through Sept. 20, 2013.  Also affected is the Wellness canned chicken and herring with best by dates from Nov. 10, 2013, or Nov. 17, 2013.

Thiamine is essential for cats.  Early symptoms of deficiency may include decreased appetite, salivation, vomiting and weight loss.  In advanced cases, neurological symptoms can develop, including bending of the neck toward the floor, wobbly walking, circling, falling and seizures.

Consumers with products affected by the recall are urged to stop using them and call their veterinarian if their cat is displaying any of the above symptoms.

Consumers with questions can call WellPet at 877-227-9587 from 6 a.m.-4 p.m. PT Monday through Friday or visit the company website at
