Orange juice is a poor choice for cats. Beyond the sugar load shared by all juices, citrus carries oils and acids that can irritate a cat's stomach, and most cats dislike the smell anyway. A stray lick is not an emergency, but there is no reason to offer it.

Why this answer
Citrus fruits contain essential oils and psoralens that can irritate a cat's gastrointestinal tract, and the juice is also acidic and sugary. While the small amount in a lick of juice is far less than eating peel or pith, oranges are on veterinary avoid lists, and the acidity plus sugar makes orange juice a needless irritant.
Watch for
Vomiting or drooling from citrus oils and acidity
Loose stool or diarrhea
Turning away from food after a sour, sugary drink
How much is okay
None is the sensible amount; if a lick is taken it is not a crisis, but orange juice should not be offered to cats at all.
Serve it safely
Keep glasses of orange juice out of a curious cat's reach.
Do not add citrus juice to water or food.
Wipe up spills so your cat does not lap them.

Answer card
No food checked yet.
Type what your cat is eyeing — or already stole — and the answer lands right here, without leaving the page.
Remove access. Take the food away and move your cat to another room.
Note the facts. What was it, roughly how much is missing, and when? Keep the packaging.
Call before symptoms. For chocolate, onion, garlic, grapes, raisins, alcohol, or anything sugar-free (xylitol), call a hotline or your veterinarian now — early treatment is easier and cheaper.
Never do this
Do not induce vomiting, feed milk, salt, or oil, or wait overnight to "see how it goes". Signs of chocolate or Allium poisoning can take hours to days to appear.
Go to an emergency vet immediately if
Your cat is collapsing, twitching or seizing, struggling to breathe, drooling heavily, vomiting repeatedly, or wobbly on their feet.
