Can cats eat lemon, lime & grapefruit?

Avoid

Strong acid and oils irritate the gut — watch lemon-scented cleaners and diffusers too.

Don't.

Why

The most concentrated citrus oils and acid — vomiting, diarrhea, drooling. Grapefruit also contains drug-interacting compounds. Lemon essential oil and diffusers are a bigger hazard (see essential oils).
