Cats fed product with the previously listed Production Codes and Best By dates exclusively for several weeks may be at risk for developing a thiamine deficiency. Thiamine is essential for cats in maintaining normal nervous system function. Symptoms of thiamine 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, neurological signs can develop, which may include ventriflexion (bending towards the floor) of the neck, wobbly walking, falling, circling and seizures. Pet owners should contact their veterinarians immediately if a cat is displaying any of these signs. If treated promptly, thiamine deficiency typically is reversible.
