My 3 kg indoor cat ate one tangerine segment — is she in trouble?

Short answer

Not likely. One segment is a very small amount for a 3 kg cat, and the flesh itself isn't toxic — only the peel's essential oils cause stomach upset. Watch her over the next few hours for vomiting or diarrhea. If anything seems off, give your own vet a call.

Same as other citrus — the essential oils in the peel cause stomach upset.

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

Tangerine 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.
