Here's the short version: the small dried anchovies sold at the grocery store and the ones made for cats look almost identical, but they differ completely in sodium content and processing — pick the wrong one and it can actually harm your cat's health.
Is it okay to give cats anchovies as a treat?
Anchovies themselves aren't a bad ingredient for cats. They're high in protein and low in fat, and rich in taurine, an amino acid that supports heart and eye health in an obligate carnivore like a cat. Their strong palatability also makes them a popular topper among owners looking to encourage a picky eater. That said, safety depends heavily on which anchovies you choose and how you prepare them, so it's worth checking the details below before feeding them.
Why are the anchovies sold for human snacking risky?
The small dried anchovies sold for stir-frying or braising at the grocery store are often salted during processing, and relative to a cat's small body size, that sodium content is quite high. Because cats are so much smaller than people, even a small amount can lead to excessive sodium intake, and repeated exposure over time can strain the kidneys or throw off fluid balance. On top of that, the stir-fry variety is often coated in oil, garlic, or seasoning, and garlic is a well-known food that can trigger hemolytic anemia in cats. Even though it looks like plain dried fish, there's a real chance these additives were introduced during processing, so sharing anchovies straight from your own dinner table is something to avoid.
How should I choose cat-safe anchovies?
Even the same fish is processed differently when made for pets, so check these 3 criteria when buying:
- Unsalted or low-sodium labeling: look for products explicitly marked "no salt added" or made for pets
- Simple ingredient list: choose single-ingredient products with no seasoning, oil, or garlic powder added
- Size and drying method: small anchovies with fewer bones, either air-dried or freeze-dried, are safer to feed
Checking these three points helps you find a product that's genuinely different from — and safer than — the grocery-store kind.
How should I prepare them before feeding?
Even with a pet-safe product, a bit of prep makes feeding safer. Start by rinsing them briefly in lukewarm water to wash off any fine residual salt or dust on the surface. Then press on the anchovies with your fingers to check for any hard, sharp bones, and remove them if you find any before feeding. Small pieces can be fed as-is, but for a senior cat or one with weak teeth, crushing them into smaller bits or a powder to sprinkle over food like a topping is a good alternative.
What's a reasonable daily amount and frequency?
Anchovies are a treat, not a staple food, so for an adult cat around 4–5kg, about 2–3 anchovies a day, fed 2–3 times a week, is a reasonable guideline. Rather than feeding daily, using them occasionally to boost interest in food or as a reward treat helps prevent sodium from building up. If it's your cat's first time, start with about half an anchovy, confirm there's no adverse reaction, and increase gradually from there. If your cat is on a low-sodium diet for kidney or heart disease, always check with your vet before adding anchovies.
What reactions should I watch for after feeding?
For a day or two after the first feeding, watch for vomiting, diarrhea, unusually high water intake, or a change in urination. If your cat starts drinking noticeably more water than usual, that can be a sign of excess sodium intake, and it's a good idea to reduce the amount or pause feeding for a while. If your cat keeps pawing at its mouth or drooling excessively, consider the possibility that an unremoved bone got lodged in the mouth or throat. If these symptoms recur or worsen, don't wait it out on your own — a vet visit is the safer call.
