Is Lime safe for cats?
Citrus aurantifolia
The lime tree is a citrus species known for its aromatic foliage and fruit. While popular as a houseplant, all parts of the plant contain essential oils and psoralens that can be harmful to pets if ingested.

Safety status
What this means for your cat
Cats should stay away from lime trees, peels, and leaves. The ASPCA lists Citrus aurantifolia as toxic to cats because of its essential oils and psoralens. Cats are particularly poor at metabolizing citrus oils — concentrated peel and leaves are far worse than a lick of pulp.
What to watch for
Vomiting, diarrhea, and depression are the main signs the ASPCA lists. Drooling and pawing at the mouth from the bitter taste are common, and skin contact with crushed peel or oils can cause dermatitis.
Time window
GI signs typically begin within a few hours of ingestion; the ASPCA does not publish a specific recovery window for lime in cats.
When to call the vet
Call your vet if vomiting is repeated, your cat is unusually flat, wobbly, or hiding, or if a skin reaction is spreading. Any noticeable change in behaviour after a chew is reason enough to call.
