Can Cats Eat Dill?

Yes — plain dill is considered non-toxic to cats. Small amounts are unlikely to cause harm, but too much plant material can still cause stomach upset, and dill should only be an occasional treat.

Dill is generally safe for cats in small amounts

ASPCA lists dill as non-toxic to cats. If your cat nibbles a small amount of plain fresh or dried dill, serious poisoning is not expected, but eating a lot of any plant material may still lead to vomiting, diarrhea, or drooling.

How to Safely Feed Dill to Your Cat

Because cats are obligate carnivores, dill should only be a tiny garnish rather than a meaningful part of the diet. If you offer it, keep it plain, use very small amounts, and avoid seasoned foods or concentrated herb products.

  • Offer only plain dill — fresh or dried — with no garlic, onion, salt, vinegar, or creamy sauce
  • Start with a very small pinch mixed into food to see whether your cat tolerates it
  • Do not let treats or toppers, including dill, make up more than 10% of your cat's daily calories
  • Avoid dill pickles and pickle brine because they are high in sodium and often contain garlic or onion
  • Do not give dill essential oil or concentrated herbal extracts to cats, because cats are more sensitive to essential oils than dogs

Common Questions

Is dill toxic to cats?
Plain dill is listed by ASPCA as non-toxic to cats. That said, eating too much of any plant can still cause mild gastrointestinal upset, so it is best offered only in tiny amounts, if at all.
Can cats eat fresh dill or dried dill?
Yes, both fresh and dried plain dill are generally considered safe in small amounts. Fresh dill should be washed, and either form should be given only as a tiny sprinkle rather than a full serving.
Can cats eat dill pickles?
Dill pickles are not recommended for cats. The problem is usually not the dill itself but the sodium, vinegar, and common seasoning ingredients such as garlic or onion, which can be harmful to cats.
How is dill different for cats versus dogs?
Dill is considered non-toxic to both cats and dogs, but cats are generally more sensitive to concentrated essential oils and are less suited to plant-based treats because they are obligate carnivores. A cat-safe amount should stay very small.
What should I do if my cat ate a lot of dill?
Monitor for vomiting, diarrhea, drooling, or decreased appetite, and call your vet if any symptoms develop or if your cat ate dill in a seasoned dish. If there is any chance the food also contained onion, garlic, or other toxic ingredients, contact your vet right away.
