Detailed Safety Information
Cooked herring is rich in Omega-3 and safe in small amounts. However, raw herring contains thiaminase which destroys vitamin B1 (thiamine). Cats are especially vulnerable: a raw fish diet can cause severe thiamine deficiency in 23-40 days (neurological symptoms, ataxia, death). Heat inactivates thiaminase — must be fully cooked. Remove all bones. Avoid salted, pickled, or smoked herring.
Higher phosphorus — limit for kidney disease.
