My 3 kg small cat licked a cut lime wedge once. Should I be worried about the citrus oils?

Short answer

A single lick from a small cat is low risk but warrants watching. Limes are acidic and the peel contains oils that can irritate a cat's mouth and stomach, potentially causing drooling or an upset stomach. Because your cat is so small, even a tiny amount of these compounds could be more noticeable. Just keep an eye out for excessive drooling, vomiting, or diarrhea over the next few hours. If you see any of those signs, or if your cat seems unusually quiet, it's a good idea to call your own vet.

Same as lemon — acidic, and the peel oils cause drooling, vomiting and diarrhoea.

Dogs and cats carry the same rating (Feed with care), so the notes below hold for either pet.

Lime is not poisonous to cats, but it is easy to over-feed. Rich fat, salt or seasoning can bring on vomiting or diarrhoea within a day, and repeated large portions are a recognised trigger for pancreatitis.

If it ate some before you noticed, watch for vomiting, diarrhoea, loss of appetite, unusual tiredness or a painful, swollen abdomen over the next 24 hours. A one-off small amount in a healthy adult usually passes with water and rest; repeated exposure, a puppy or kitten, a senior, or a pet with an ongoing illness is a reason to call your vet the same day.
