Can Cats Eat Oranges?

No — oranges are not a good food for cats. While a tiny lick of the flesh may only cause stomach upset, the peel, leaves, and plant material contain citrus oils and psoralens that are toxic to cats.

Urgent

Orange peel and plant parts are toxic to cats

ASPCA lists orange as toxic to cats because of essential oils and psoralens. The fruit flesh is edible, but it is not recommended for cats and can still cause gastrointestinal upset, while peels, seeds, leaves, and other plant material pose a higher risk.

How urgent is this?

  • Signs of an intestinal blockage, such as repeated vomiting, abdominal pain, or inability to keep food or water down after eating peel or large pieces
Urgent

See a vet within 24 hours

  • Cat ate orange peel, leaves, rind, or a concentrated citrus product

  • Cat licked a very small amount of orange flesh and is acting normal
  • Brief lip-smacking or mild dislike after tasting orange with no ongoing symptoms

Why Oranges Are Dangerous for Cats

Cats are more sensitive than dogs to many plant compounds and essential oils. Merck notes that cats are especially at risk from essential oil toxicosis because they are deficient in glucuronyl transferase, and ASPCA lists orange as toxic to cats due to essential oils and psoralens. Even though the fruit flesh is technically edible, oranges are not an appropriate treat for an obligate carnivore and may still upset the stomach.

  • The peel, leaves, stems, and other plant material contain essential oils and psoralens that can be toxic to cats
  • Orange flesh is not a necessary or ideal treat for cats and may cause vomiting, diarrhea, or drooling
  • Cats are more vulnerable than dogs to essential oil exposure because of differences in metabolism
  • Tough peel and rind can also be hard to digest and may increase the risk of gastrointestinal irritation or blockage
  • If your cat ate orange peel, plant material, or citrus oil, call your vet for guidance rather than offering more food

Common Questions

Can cats eat orange flesh?
Orange flesh is considered edible in small amounts, but it is not recommended for cats. Cats do not need fruit in their diet, and even a small amount may cause stomach upset because oranges are acidic and not well suited to feline nutrition.
Are orange peels toxic to cats?
Yes. Orange peels are more concerning than the flesh because they contain concentrated citrus essential oils and psoralens. ASPCA lists orange as toxic to cats, and peels can also irritate the stomach and be difficult to digest.
Why are cats more sensitive to citrus than dogs?
Cats are especially sensitive to many essential oils because they have limited glucuronidation capacity. Merck Veterinary Manual notes that cats are at particular risk for essential oil toxicosis, which helps explain why citrus oils can be more dangerous for cats than for dogs.
What symptoms can happen if a cat eats orange or orange peel?
Possible signs include vomiting, diarrhea, drooling, depression, and skin irritation if there was direct contact. More significant exposure to peel, plant parts, or citrus oil can cause more serious illness, so contact your veterinarian if symptoms develop.
Can cats have orange juice or citrus essential oils?
No. Orange juice is not a good choice for cats because it is acidic and sugary, and citrus essential oils are more dangerous because cats are highly sensitive to them. Keep citrus oils, diffusers, and concentrated products away from cats.
