What to do after ingestion
Vomiting, drooling, diarrhoea, poor appetite, lethargy and hiding, with more obvious mouth irritation after contact with the peel or its oils.
**Contact a vet immediately** if a cat ate kumquat peel, seeds or any citrus oil product, and never induce vomiting at home.
A kumquat is a citrus fruit, and **citrus peel and oils hold limonene and other irritants** that cats are especially sensitive to, while the seeds and stem end are unsafe too; cats need no fruit, so the safest choice is none at all.
What to do after ingestion
Vomiting, drooling, diarrhoea, abdominal discomfort, poor appetite and lethargy; eating a lot of peel or any essential-oil product adds more marked mouth and gut irritation or depression.
A small piece of flesh means stopping the treat and watching; **contact a vet immediately** after more peel, seeds or any essential-oil product, or for continuing vomiting, drooling or lethargy, and never induce vomiting at home.
A kumquat is a citrus fruit: **the peel, seeds and essential oils hold limonene and other irritants**, so a large helping can irritate the mouth and gut; a little peeled flesh should cause no more than mild stomach upset.

For cats the answer is none at all; candied kumquats and marmalade are unsuitable too as they are sugary and may contain alcohol or preservatives, so keep fruit bowls out of reach and any treat within about 10% of daily energy intake.

Offer only a tiny peeled piece of flesh and **never a whole kumquat**, since the peel's oils irritate; skip candied kumquats and marmalade, which are sugary and may contain alcohol, and keep treats within about 10% of daily energy intake.
