Why this answer
Limes share lemons' hazards — citric acid, limonene and other essential oils, and psoralens concentrated in the rind. In a cat these irritate the mouth and gut and, at high intake, can affect the nervous system. Key lime desserts also add sugar and dairy that do a cat no favors.
Watch for
Drooling or mouth discomfort
Vomiting or loose stool
Reduced appetite
Low energy after a larger amount
How much is okay
None needed — cats have no use for lime; keep the fruit, juice, and zest away rather than sharing any.
Serve it safely
Keep lime wedges and peels off counters and tables a cat reaches.
Do not add lime juice to a cat's food or water.
Put used rinds in a covered bin, not an open bowl.

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.
