A 4-pound cat nibbled a tangerine segment with some white pith and peel about an hour ago — will she be okay?

Short answer

It is okay, but a little caution is needed here. The flesh of a single segment is low risk for a cat her size, yet the white pith and peel carry essential oils that can irritate a cat's stomach and mouth. Watch her over the next few hours for drooling, mild vomiting, or a reluctance to eat — these signs usually pass on their own. Strip the fruit to just the flesh and skip the peel next time; call your own vet if vomiting persists or she seems unusually quiet or uncomfortable.

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.
