Can Cats Eat Cashews?

Yes, but with caution — plain, unsalted cashews are not considered specifically toxic to cats, but they are not an ideal food for an obligate carnivore and can cause stomach upset or other problems if overfed.

Cashews are not toxic, but they are not a great cat treat

A small piece of plain cashew is unlikely to poison most cats. The bigger concerns are gastrointestinal upset, high fat and calories, choking risk, and added ingredients like salt, chocolate, garlic, onion, or xylitol in seasoned nuts or cashew butter.

How urgent is this?

Emergency

Go to the ER now

  • ● Trouble breathing, repeated choking, or a cashew seems stuck in the mouth or throat
  • ● Collapse, seizures, severe weakness, or unresponsiveness
  • ● Your cat ate cashews coated with chocolate, garlic, onion, or another known toxic ingredient
Urgent

See a vet within 24 hours

  • ● Repeated vomiting or diarrhea after eating cashews
  • ● Your cat ate a large amount, especially salted, seasoned, or buttered cashews
  • ● Your cat has abdominal pain, marked lethargy, or stops eating after eating cashews
  • ● Your cat ate cashew butter or a snack product with unknown ingredients
Monitor

Watch at home, call if it worsens

  • ● Your cat ate a tiny amount of plain, unsalted cashew and is acting normal
  • ● There is only mild, brief stomach upset and your cat is otherwise comfortable
  • ● You can confirm the cashew was plain and there were no toxic flavorings or sweeteners

How to Safely Feed Cashews to Your Cat

Cashews should be an occasional taste only, not a regular treat. Because cats are obligate carnivores, nutritionally complete cat food should make up the vast majority of the diet.

  • Only offer plain, unsalted cashews with no chocolate, garlic, onion, spices, or sweeteners
  • Give only a very small amount — a crumb or tiny piece is plenty for most cats
  • Avoid whole cashews because they can be a choking hazard; break any piece into very small bits
  • Do not give cashew butter unless you have checked every ingredient carefully and your vet says it is appropriate
  • Skip cashews entirely for cats with a history of digestive sensitivity, pancreatitis, obesity, or on a prescription diet

Common Questions

Are cashews toxic to cats?
Plain cashews are not generally listed as a specific toxin for cats. However, they are high in fat, easy to overfeed, and can cause stomach upset. Flavored or mixed nut products may be much more dangerous because they can contain salt, chocolate, onion, garlic, or xylitol-containing ingredients.
How many cashews can a cat eat?
If you choose to share cashew at all, keep it to a very small taste only. For most cats, a tiny piece is enough. Cashews should not be a routine snack because cats do not need nuts in their diet and the extra fat and calories can cause problems over time.
Can cats eat salted or seasoned cashews?
No. Salted, honey-roasted, chocolate-covered, garlic-seasoned, onion-seasoned, or spicy cashews should be avoided. Seasonings and coatings add unnecessary risk, and some ingredients commonly used in snack foods are toxic to cats.
Is cashew butter safe for cats?
Usually best avoided. Even if the cashew itself is not toxic, nut butters may contain added salt, sugar, oils, or xylitol-containing sweeteners in mixed products. They are also very calorie-dense and not appropriate as a regular cat treat.
How is this different from dogs?
Cashews are also not considered one of the classic toxic nuts in dogs, but cats are generally less suited to plant-based treats because they are obligate carnivores. High-fat foods are still a concern in both species, but cats should get even less of foods like nuts, and many human snack ingredients are especially problematic for them.
