Cats fed only the affected lots for several weeks may be at risk for developing a thiamine deficiency. Thiamine is essential for cats. Symptoms of deficiency displayed by an affected cat can be gastrointestinal or neurological in nature. Early signs of thiamine deficiency may include decreased appetite, salivation, vomiting, and weight loss. In advanced cases, neurologic signs can develop, which may include ventriflexion (bending towards the floor) of the neck, wobbly walking, circling, falling, and seizures. If your cat has consumed the recalled lots and has these symptoms, please contact your veterinarian. If treated promptly, thiamine deficiency is typically reversible.
