Pistachios are not a good cat snack. In small plain amounts they are not known as a poison, but they can still cause stomach upset, and the shell is a real choking or blockage risk. Salted, flavored, honey-roasted, or seasoned pistachios are worse because cats should not be eating salty snack foods or added seasonings.

Why pistachios are a bad idea for cats
Cats are obligate carnivores, so nut snacks do not give them anything they need. Pistachios are also fatty, and a larger amount can upset the stomach. The bigger concern is the shell: if a cat chews or swallows it, the pieces can choke the cat or get stuck in the digestive tract.
Salt is another problem. Cats do not need salty snack foods, and the extra seasoning on human pistachios can add ingredients that are not cat-safe.
What to do if your cat stole one
- Take the nuts away and check whether your cat ate a shell.
- If it was one plain kernel and your cat is acting normal, monitor for vomiting, diarrhea, drooling, or refusing food.
- If the pistachio was salted, seasoned, coated, or eaten with shell pieces, call your veterinarian for advice.
- Get help right away if you see repeated vomiting, belly pain, lethargy, constipation, trouble breathing, or signs that something is stuck.

Bottom line
A single plain pistachio kernel is usually more of a stomach-upset concern than an emergency, but pistachios should not become a treat. The shell, salt, and seasoning are the parts that make this snack risky, so keep pistachios out of reach and stick to cat-safe food instead.
