Is asparagus safe for cats?

Asparagus is a green spear vegetable, tender when cooked and woody when raw. The vegetable itself is not toxic, but the ornamental asparagus fern plant is toxic to cats, so do not confuse the two. Cats are obligate carnivores, so they get what they need from meat and never need asparagus. If you offer it at all, treat it as a rare, tiny extra.

How to serve asparagus to your cat

What to avoid

How much asparagus can my cat have?

Offer just a tiny taste, about a fingernail-sized piece, once in a while. Treats, including asparagus, should stay under about 10% of your cat's daily calories.

Signs your cat may be having a problem

Watch for vomiting, diarrhea, drooling, pawing at the mouth, loss of appetite, tiredness, a swollen or painful belly, or trouble breathing. Contact your vet right away if you see these signs, or if your cat has eaten any of the parts listed above.

Emergency? Call your vet or an animal poison hotline straight away: ASPCA Animal Poison Control (888) 426-4435 or Pet Poison Helpline (855) 764-7661 (US numbers, a consultation fee may apply).

Frequently asked questions

Can kittens eat asparagus?

Young animals have more sensitive digestive systems and a carefully balanced diet, so check with your vet before adding asparagus. If you get the go-ahead, start with an even smaller amount than an adult would get.

What if my cat ate too much asparagus?

The most common result is an upset stomach with vomiting or diarrhea. Offer water, skip further treats, and call your vet if symptoms are severe or last more than a day, or if your cat ate any of the parts listed under "What to avoid".

How often can my cat have asparagus?

Treat it as an occasional extra rather than a daily food. Once or twice a week at most is a sensible starting point for a healthy adult cat, and less for small ones.
