Are Oranges Toxic to Cats?
Yes. Oranges — including the flesh, peel, seeds, and even the plant — are toxic to cats. Along with oranges, cherries is one of the toxic fruit that you should avoid giving to your cat
Cats should never consume:
- Oranges
- Mandarins
- Tangerines

Why Are Oranges Dangerous for Cats?
Oranges contain three major substances that are harmful to cats and besides oranges if you are wondering which other fruits are toxic to your cats then pineapple is also considered harmful for your cats.
1. Essential Oils
Oranges contain high levels of citrus essential oils such as limonene and linalool.
Cats lack the liver enzymes to break these down.
Effects include:
- Drooling
- Vomiting
- Tremors
- Liver stress
2. Psoralens
These natural chemicals make skin sensitive to light and can cause toxicity when ingested.
Symptoms include:
- Stomach upset
- Skin irritation
- Depression
- Light sensitivity
3. High Acidity
Oranges are extremely acidic.
In cats, acidity causes:
- Stomach pain
- Vomiting
- Diarrhea
- Mouth irritation
Because of these dangers, oranges should never be part of a cat’s diet — not even a small piece.
Can Cats Eat Orange Flesh?
No — even the soft part of the fruit can cause illness.
While humans enjoy the sweetness, the combination of acids, essential oils, and sugar makes oranges unsafe
Can Cats Eat Orange Peels?
Definitely not.
Orange peels contain even higher levels of essential oils than the fruit. They can cause:
- Drooling
- Vomiting
- Diarrhea
- Severe irritation
- Liver toxicity
Also, the tough peel is a choking hazard.
Can Cats Eat Orange Seeds?
No. Orange seeds contain toxic plant compounds and pose a choking risk.
Can Cats Drink Orange Juice?
No — orange juice is even more dangerous because:
- It’s concentrated
- Extremely acidic
- Loaded with sugar
- Contains citrus essential oils
Never offer your cat orange juice.
Symptoms of Citrus Toxicity in Cats
If your cat eats oranges or any citrus fruit, symptoms may appear within 30 minutes to 2 hours.
Look for:
- Vomiting
- Diarrhea
- Drooling
- Weakness
- Tremors
- Low energy
- Difficulty walking

- Rapid breathing
- Collapse in severe cases

What to Do If Your Cat Eats Oranges?
If your cat licks, bites, or eats orange flesh, peel, or products:
1. Call your veterinarian immediately
Even small amounts can be dangerous.
2. Contact a pet poison hotline
- ASPCA Poison Control
- Local emergency vet hospital
3. Do NOT induce vomiting unless a vet advises it
This can sometimes worsen the irritation.
4. Remove any remaining fruit or juice from your cat’s mouth
Wipe gently with a damp cloth.
5. Monitor closely for symptoms
Even if your cat seems fine, toxicity may develop later.
Why Cats Naturally Avoid Oranges
Interestingly, most cats hate the smell of citrus — and this is a good thing!
Cats instinctively avoid:
- Citrus smell
- Orange peels
- Orange essential oils
- Lemon-scented cleaners
This natural dislike helps protect them from consuming anything harmful.
If your cat dislikes oranges, that’s normal and healthy.
Why Cats Can’t Process Citrus Oils
Cats lack a liver enzyme called glucuronyl transferase, which is essential for breaking down chemicals found in citrus oils.
Because their liver cannot metabolize these substances, toxins build up quickly, leading to illness.
This is why all citrus essential oils are dangerous for cats — including diffusers, candles, and sprays.
Are Any Citrus Fruits Safe for Cats?
No.
All citrus fruits — even mild ones like tangerines or mandarins — contain toxic oils and acids.
Cats should avoid:
- Citrus fruits
- Citrus-flavored drinks
- Citrus candies
- Foods cooked with citrus
- Citrus essential oils
- Citrus cleaners
None of these are safe.
Healthy Alternatives to Oranges for Cats
Instead of oranges, offer your cat safe treats like:
✔ Cooked chicken
✔ Tuna flakes (unsalted)
✔ Freeze-dried fish
✔ Plain boiled egg (tiny amount)
✔ Catnip
✔ Commercial cat treats
These treats are more natural and safer for their carnivorous diet
