Short answer: no, cats should not eat limes. The ASPCA lists lime as toxic to cats, with essential oils and psoralens as the main toxic principles. The biggest concern is the peel, zest, leaves, stems, seeds, and any concentrated lime oil. Even the fruit itself can irritate a cat’s mouth or stomach, so it is not a safe treat.
Why limes are a bad idea for cats
Limes are citrus fruits, and citrus can be rough on cats. The ASPCA lime entry says the fruit is edible in small amounts, but the skins and plant material can cause problems. The ASPCA also notes that citrus stems, leaves, peels, fruit, and seeds contain citric acid and essential oils that can cause irritation and, in larger amounts, depression.
That means the main issue is not just acidity. The oils in citrus peel and zest are the bigger hazard, and cats are especially sensitive to essential oils in general. The acidity can still add to mouth and stomach irritation, especially if a cat chews peel, drinks lime juice, or gets lime oil on the coat and then grooms it off.
Symptoms to watch for
Most mild exposures cause drooling, lip smacking, vomiting, diarrhea, or not wanting to eat. The ASPCA lists vomiting, diarrhea, depression, and possible dermatitis for lime exposure. More serious essential-oil exposures can also cause wobbliness, tremors, breathing trouble, or other nervous system signs.
Symptoms matter more than the exact amount in many cases. If your cat only licked a small amount of lime flesh and is acting normal, the risk is usually lower than with peel, zest, or oil. But if your cat swallowed peel, drank lime juice, licked essential oil, or is showing any symptoms, do not wait and see for long.
What to do if your cat ate lime
Remove the lime or any lime-flavored food from reach. Do not induce vomiting unless a veterinarian or poison-control expert tells you to. If lime oil got on your cat’s fur or paws, keep your cat from grooming and call for advice right away.
Contact your veterinarian or a poison hotline if your cat ate peel, zest, seeds, or any concentrated lime product; if your cat is vomiting, drooling, or lethargic; or if your cat has breathing trouble, tremors, weakness, or a seizure. In the U.S., you can call the ASPCA Animal Poison Control Center at (888) 426-4435 or your local poison hotline.

Bottom line: keep limes out of your cat’s reach. A tiny accidental lick is usually less concerning than peel or oil exposure, but limes are still not a cat-safe food.
