Celery is generally safe for cats in small amounts

Plain celery is not considered toxic to cats, and some veterinary guidance lists de-stringed celery as a safe treat option. Because cats are obligate carnivores, celery should only be an occasional snack rather than a meaningful part of the diet, and large or stringy pieces can be a choking or digestive hazard.

How to Safely Feed Celery to Your Cat

If your cat likes celery, keep it plain, washed, and very small. Celery is not nutritionally necessary for cats, so offer only a tiny amount and keep all treats under 10% of your cat’s daily calories.

  • Wash celery thoroughly before serving
  • Remove tough strings and cut into very small pieces to lower choking risk
  • Serve plain only — no dips, salt, butter, onion, garlic, or seasoning
  • Offer a tiny bite or two as an occasional treat, not a meal replacement
  • Stop feeding it if your cat develops vomiting, diarrhea, or seems uninterested

Common Questions

Is celery toxic to cats?
Plain celery is generally considered non-toxic to cats. The bigger concerns are mechanical ones: stringy fibers can be hard to chew, large pieces may pose a choking risk, and too much plant matter can upset a cat’s stomach.
Why is celery different for cats than for dogs?
Celery itself is not known to be more toxic to cats than dogs, but cats are obligate carnivores and usually have less nutritional reason to eat vegetables. Cats may also be less tolerant of diet changes, so even safe foods like celery are best kept to very small amounts.
Can cats eat celery leaves?
The stalk is the better-supported option in veterinary guidance. If celery is offered, plain de-stringed stalk in tiny pieces is the safest practical choice, and many cats do not need or benefit from celery leaves.
How much celery can I give my cat?
Only a very small amount — think tiny chopped pieces as an occasional treat. Treats and extras should stay under 10% of your cat’s daily calories, and your cat’s main nutrition should come from a complete and balanced cat food.
What symptoms should I watch for after my cat eats celery?
Watch for gagging, coughing, vomiting, diarrhea, drooling, constipation, abdominal discomfort, or reduced appetite. If your cat seems unwell, especially after eating a large piece or celery prepared with onions, garlic, or seasoning, call your vet.
