Starfruit

Averrhoa carambola
Also known as:carambola, star fruit
CatCaution

The oxalate and neurotoxin in starfruit are cleared by the kidneys, so **cats with kidney disease must never eat it**; it builds up and can cause hiccup-like movements, vomiting and seizures. Cats need no fruit, so healthy cats are best not fed it either.

DogCaution

Starfruit holds oxalate and a neurotoxin (caramboxin) that healthy animals clear via the kidneys; **pets with kidney disease must never eat it**, as it builds up and causes hiccup-like movements, vomiting and seizures. Healthy dogs get a tiny peeled piece.
