Can Cats Eat Tuna in Oil? No, Choose Water-Packed

Choose water-packed

No. Skip tuna in oil and choose plain water-packed tuna if tuna fits your cat.

Next stepUse plain water-packed tuna, drained well, and keep it tiny.

Call for seasoning or symptoms

Call your veterinarian if tuna in oil included onion, garlic, bones, heavy seasoning, a large amount of oil, or symptoms start.

Do not rinse and hope

Oil clings to tuna. It is simpler and cleaner to choose plain water-packed tuna or skip the treat.

Watch rich-food symptoms

Oil can cause stomach upset, and rich foods are not a good choice for cats with medical diets or digestive issues.

If your cat ate it

  • Do not serve tuna packed in oil.
  • If your cat already ate some, note the amount, oil type, seasoning, salt, and whether vomiting or diarrhea starts.

Skip oily and flavored tuna

  • Oil-packed tuna, flavored tuna, brine, salt, onion, garlic, lemon pepper, tuna salad, mayonnaise, and frequent tuna treats.
  • Trying to rinse oily tuna and treat it as plain. Use a different can if you choose tuna at all.

Watch

  • Vomiting, diarrhea, drooling, low appetite, belly pain, lethargy, hiding, or behavior that feels wrong.

Portion

No intentional serving. If tuna is used at all, use a tiny amount of plain water-packed tuna.
