Is Citrus toxic to cats?
Citrus (Citrus spp.) is toxic to cats. The agent is essential oils (limonene, linalool) and psoralens.
ASPCA Animal Poison Control, 24 hours: (888) 426-4435 (a consultation fee may apply), or call your own vet. Take a piece of the plant with you.
Signs that need a vet the same day whatever the plant: repeated vomiting, drooling that will not stop, swelling of the mouth or face, trouble breathing or swallowing, collapse, or a seizure.
What it does, and why
Citrus contains essential oils (limonene, linalool) and psoralens. The compound sits in the sap, so the plant does the most harm when it is broken — chewed, snapped, or pruned. Skin contact can irritate as well as ingestion.
Signs to watch for
Vomiting, diarrhea, depression; skin irritation. Peel and leaves are the problem, not the flesh of the fruit.
How likely is it, really
Most cases are a chewed leaf rather than a meal. The dose matters: a nibble and a swallowed stem are different events. Volume, and how long ago, are the two things the vet will ask.
Keeping the plant anyway
Height alone does not work with a cat — a cat treats a high shelf as a destination. What actually helps: a room the cat does not have unsupervised access to, a hanging position with no adjacent launch point, and clearing fallen leaves the same day, since a dropped leaf on the floor is the usual culprit. A pot of cat grass elsewhere in the room redirects the urge to chew far better than deterrent sprays do.
Is it toxic to people?
No meaningful hazard to people from handling Citrus. Ordinary care with small children still applies — anything chewed in quantity can cause a stomach ache.

Sources and how we checked
This species is not listed under a name we could resolve in ASPCA's database, so the record above comes from standard horticultural and veterinary references and is marked unconfirmed. We do not present an unconfirmed plant as safe. The full list is at aspca.org.
This is general information, not veterinary advice. Any animal that is actually unwell needs a vet, not a web page.
