Can Cats Eat Celery? 2026 Vet Guide
Quick Answer: ✓ YES — Safe for Cats
Yes — celery is safe for cats, and some cats are attracted to it.
The cat-celery relationship is one of the more curious observations in feline behavior. A subset of cats show an unusual affinity for celery—some will seek it out and rub their faces on it, similar to catnip behavior. Research suggests this response is triggered by phthalide compounds in celery that may structurally resemble feline pheromones.
Nutritional Facts & Benefits
Celery contains vitamins A, C, and K, potassium, and fiber. Interestingly, some cats are attracted to celery—it contains phthalides, compounds with aromatic properties that some felines find intriguing. It is very low in calories.
Risks to Know
Celery strings can be a choking hazard. Large amounts may cause loose stools. Most cats will not seek out celery actively.
How to Serve Celery to Cats Safely
Cut celery into very small pieces, removing tough strings. A few tiny pieces at most. Most cats will sniff and walk away.
How Much Celery Is Safe for Cats?
A few tiny pieces as an occasional treat for cats that show interest.
Celery vs Carrots
Both celery and carrots are popular low-calorie crunchy vegetables for dogs. Carrots provide more beta-carotene and are slightly sweeter, making them more universally accepted by dogs. Celery provides more water content (95% vs 88%) and contains unique compounds called phthalides that have been linked to cardiovascular benefits in research. Alternating between the two provides nutritional variety.
Phthalides and Feline Behavior
The specific phthalide compound thought to trigger some cats’ celery response is 3-n-butylphthalide. Research on the nepetalactone-like activity of phthalides in cats is limited, but anecdotal reports of celery ‘catnip response’ are widespread. Not all cats respond—the response to nepetalactone (catnip) and its structural analogs is genetic, with approximately 50–65% of cats inheriting the responsive gene. Celery is safe for cats that enjoy it, and for those that do respond, it can provide enrichment similar to catnip.
Frequently Asked Questions
Q: Why does my cat like celery?
Some cats find the aromatic compounds in celery—specifically phthalides—similar in structure to compounds in catnip. This is not universal, but some cats do show an affinity for celery.
Q: Is celery as good as catnip for cats?
No. Catnip’s nepetalactone provides a much more pronounced feline response. Celery is just a benign vegetable that some cats are mildly curious about.
Q: Can cats eat celery leaves?
Celery leaves are not toxic to cats. They are more bitter and most cats will ignore them, but they are safe.

A few teaspoons of plain celery juice without additives is not toxic. However, it has no meaningful benefit for cats and water is always the best hydration.
