Can Cats Eat Anchovies?

Yes — in small amounts, plain anchovies can be a safe occasional treat for cats. The main concerns are excess salt, oil, bones, and added seasonings like garlic or onion, which are especially dangerous for cats.

Plain anchovies are usually safe for cats in tiny amounts

Because cats are obligate carnivores, small amounts of plain fish can fit as an occasional treat. However, anchovies packed in salt, oil, or seasoning are less ideal, and garlic or onion flavorings are more toxic to cats than to dogs.

How to Safely Feed Anchovies to Your Cat

If you offer anchovies, keep them plain, tiny, and occasional. Treats should make up only a small part of your cat’s daily calories, and human fish products should not replace a complete and balanced cat diet.

  • Choose plain anchovies packed in water, with no garlic, onion, chives, spicy seasoning, or sauces
  • Rinse canned anchovies to lower surface salt before offering a small bite
  • Offer only a tiny piece or one small anchovy as an occasional treat, not a meal
  • Avoid frequent feeding of salty or oily anchovies, which can upset the stomach and add unnecessary sodium and fat
  • Use caution with bones; if you are unsure, choose boneless fish or call your vet before feeding

Common Questions

Are anchovies safe for cats?
Usually yes, if they are plain and fed in very small amounts as an occasional treat. The biggest risks are excess salt, added oils, and seasonings such as garlic or onion, which are especially toxic to cats.
How many anchovies can I give my cat?
Keep it very small — usually a tiny piece or one small plain anchovy is enough for a treat. Anchovies should not replace a complete and balanced cat food, and treats should stay limited.
Can cats eat canned anchovies?
Sometimes, but only with caution. Water-packed anchovies are a better option than oil-packed or heavily salted varieties, and they should be plain with no garlic, onion, or other seasonings.
Are anchovies more risky for cats than dogs?
The general food risks are similar, but cats are especially sensitive to allium ingredients such as garlic and onion. Because cats are smaller, even small amounts of salty or seasoned anchovies can cause proportionally bigger problems.
What symptoms should I watch for if my cat ate bad anchovies?
Watch for vomiting, diarrhea, drooling, lethargy, poor appetite, belly pain, gagging, or trouble swallowing. If the anchovies were heavily salted, monitor for weakness, tremors, or seizures, and if they were seasoned with garlic or onion, call your vet promptly.
