Pistachio

Cats tolerate fat poorly and pistachios are about 45% fat, so even a few kernels can cause vomiting and diarrhoea; whole nuts and shells are a choking risk, and pistachios add nothing a cat needs.

Vomiting, diarrhoea, reduced appetite, lethargy; seek veterinary care if vomiting continues.

Stop feeding and monitor; contact a vet immediately if vomiting, abdominal pain or lethargy persists.

At most a rare pinch of plain unsalted kernel crumbs (1-2 tiny pieces); salted or sugar-coated pistachios add salt and sugar cats do not need, and the shells must never be fed.

Pistachios are roughly 45% fat, so this heavy fat load often causes vomiting and diarrhoea and can trigger pancreatitis; a whole nut chokes a small dog and the hard shells are even harder to digest.

Vomiting, diarrhoea, abdominal pain, loss of appetite, lethargy; repeated vomiting or severe abdominal pain points to pancreatitis and needs urgent care, while retching or trouble swallowing suggests choking.

A small taste of plain unsalted pistachio usually needs monitoring only; contact a vet immediately if vomiting, abdominal pain or lethargy persists or if choking is suspected.

Only plain, unsalted, unseasoned pistachio kernels crushed into small pieces, a few pieces at most; never feed the shells, and keep salted or sugar-coated pistachios away.
