Low levels of thiamine (vitamin B1) have prompted Procter & Gamble to recall certain lots of its Iams ProActive Health canned cat food.

The Cincinnati-based company said it took the "precautionary measure" after tests revealed the food may contain insufficient levels of thiamine. Proctor and Gamble says thiamine is "essential for cats."

The recall is limited to Iams ProActive Health canned cat and kitten food -- all varieties of 3 ounce and 5.5 ounce cans. The products have a date on the bottom of the cans of 09/2011 to 06/2012 and were distributed in North America.

"Cats that were fed these canned products as their only food are at greater risk for developing signs of thiamine deficiency," the company said in a written statement.

Early signs of thiamine deficiency may include loss of appetite, salivation, vomiting and weight loss, the company said. In advanced stages, symptoms can include downward curving of the neck, wobbly gait, falling, circling, and seizures.

Pet owners should contact their veterinarians if their cats display any of these symptoms. "If treated promptly, thiamine deficiency is typically reversible," the company said, adding cat owners should discard any of the recalled products.

For more information about the recall -- or a refund on the products -- pet owners can contact Procter & Gamble at 877-340-8826. More details are available on the company's Web site.
