Can cats eat grapefruit?

No Toxic

Citrus oils and psoralens are toxic to cats.

Why Citrus essential oils and psoralens

If your cat ate some

  1. A small amount usually causes nothing worse than a mild stomach upset.
  2. Offer water, skip the next treat and call your vet if vomiting or diarrhoea lasts more than a day or your pet seems unwell.
  3. For cats, or if a lot of peel was eaten, call your vet.

Signs to watch for

  • Vomiting and diarrhoea
  • Drooling
  • Depression
  • Sensitivity to light (large amounts of peel)

Dogs and cats, side by side

Dogs In moderation

Not really. A little grapefruit flesh isn’t seriously toxic, but it is very acidic and bitter, and the peel, pith and seeds contain oils and psoralens that upset the stomach.

How much: Avoid.

Cats Toxic

No. Citrus oils and psoralens are toxic to cats.

The details

Grapefruit is one of the citrus fruits most dogs will happily refuse on their own. The flesh is mostly a problem of acidity; the peel and plant carry more of the irritant oils. For cats, any citrus product, including concentrated oils and fragrances, should be avoided.

Grapefruit is also known for interacting with some human medicines. That interaction hasn’t been well studied in pets, which is another reason not to share it.
