Cats can have cabbage, but only a little, and only as plain, well‑cooked cabbage given occasionally as a treat, not as a regular part of their diet. Too much—especially raw or seasoned cabbage—can cause stomach upset and may pose health risks, so it is safest to keep portions tiny and infrequent and to ask your vet before making it a habit.

Is cabbage safe for cats?

  • Small amounts of plain, cooked cabbage are generally considered safe for healthy cats.
  • Cabbage does not provide essential nutrients cats must have, so it should never replace high‑quality meat‑based cat food.

Benefits (in tiny amounts)

  • Cabbage contains fiber, vitamins like vitamin K and C, and antioxidants that can modestly support digestion and overall health when used as an occasional extra.
  • A small bite can add variety or enrichment for cats that are curious about human food, but the nutritional gain for them is limited compared to meat.

Risks and when to avoid it

  • Too much cabbage can lead to gas, bloating, diarrhea, or constipation because cats do not digest vegetables very efficiently.
  • Raw cabbage and large or frequent portions may interfere with thyroid function due to certain natural compounds, so some guides recommend avoiding raw entirely and being extra cautious for cats with thyroid disease.

How to serve it safely

  • If your vet agrees it is okay for your cat, offer a pea‑sized piece or two of plain, cooked (steamed or boiled) cabbage with no salt, oil, butter, garlic, onion, or sauces.
  • Watch closely afterward for vomiting, diarrhea, gas, or behavior changes and stop immediately and call your vet if anything looks off.

Cabbage and popular dishes

  • Avoid giving cats coleslaw or cabbage dishes like soup or stir‑fries because they usually contain raw cabbage, salt, vinegar, sugar, onion, garlic, or fatty ingredients that can be harmful.
  • For a treat, safer options are vet‑approved commercial cat treats or tiny amounts of cat‑safe meats instead of regular vegetable snacks.

Bottom line: If you are wondering “can cats have cabbage,” the safest approach is: only rarely, only plain and cooked, only in very small amounts, and only with your vet’s blessing—because your cat’s main fuel should always be high‑quality meat‑based food.
