Overview
Some cat owners ask: can cats eat herring? The short answer is yes—but only if it’s prepared the right way.
Herring is a fatty fish, and while cats can enjoy small amounts, many common preparations make it unsafe.
Is herring safe for cats?
Plain, cooked herring is generally safe for cats in small portions.
The problem is that most herring sold for people is salted, smoked, or pickled.
- Plain cooked herring: usually safe
- Processed herring: not safe
- Treat only, not a meal
