Most nuts and seeds are not useful treats for cats. Cats are obligate carnivores, so they should get their nutrition from a complete and balanced cat food, not from pantry snacks. Nuts and seeds are often fatty, hard to chew, salty, seasoned, or attached to dangerous fruit pits.
The safest rule is simple: do not feed cats fruit pits or fruit seeds, do not offer nut mixes, and do not treat nuts and seeds as a health supplement. If your cat stole a small plain nut or seed, call your veterinarian if you are unsure, and seek urgent help for vomiting, weakness, tremors, breathing trouble, collapse, or signs of choking.
Are Nuts Good for Cats?
No. Nuts are not a good way to improve a cat’s diet. Even plain nuts can be high in fat and calories, which may cause vomiting, diarrhea, weight gain, or pancreatitis in some pets. Whole nuts can also be a choking hazard or pass poorly through a small digestive tract.
Many human nut snacks are worse than the nut itself. Salted nuts, flavored nuts, trail mix, chocolate-coated nuts, candied nuts, nut butters with xylitol, garlic-seasoned snacks, onion-seasoned snacks, and alcohol-flavored desserts should be kept away from cats.
Macadamia nuts should be avoided. They are well known as a pet toxin, especially for dogs, and cats do not need any exposure to them. Moldy nuts are also risky because molds can produce toxins that affect the digestive system or nervous system.
Can Cats Eat Seeds?
Seeds are not automatically safe just because they are small. Some seeds are hard and can irritate the digestive tract. Some are fatty. Some are sold salted or seasoned. Others are part of fruit pits that can be toxic or can block the digestive tract.
A tiny amount of plain pumpkin seed or sunflower seed is unlikely to be useful nutritionally for a healthy cat, and it may still cause stomach upset. If your veterinarian has recommended a specific product or supplement, follow their instructions. Otherwise, choose cat treats made for cats instead of guessing with pantry seeds.
Fruit Seeds and Pits to Avoid
Do not let cats eat apple seeds, cherry pits, peach pits, apricot pits, plum pits, or similar stone-fruit pits. Some of these plant parts can contain cyanide-producing compounds, especially if chewed or crushed. Pits can also be choking hazards or intestinal blockage risks.
The flesh of some fruits may be low-risk in tiny amounts after seeds, pits, stems, leaves, and peels are removed, but cats do not need fruit. Never hand a cat a whole cherry, peach, plum, apricot, apple core, or fruit pit to chew.
Nuts and Seeds to Keep Away From Cats
Keep these away from cats:
- Macadamia nuts
- Moldy nuts or seeds
- Walnuts, pecans, almonds, pistachios, cashews, peanuts, and mixed nuts offered as regular treats
- Salted, spicy, candied, chocolate-coated, garlic-flavored, onion-flavored, or xylitol-containing nut products
- Apple seeds, cherry pits, peach pits, apricot pits, plum pits, and other fruit pits
- Shells, hulls, and hard seed casings
- Trail mix, granola, baked goods, and snack bars with raisins, chocolate, xylitol, or lots of fat
This list is not a complete poison list. If your cat ate a snack mix, read the ingredients and call your veterinarian or a pet poison hotline for specific advice.
What if My Cat Ate Nuts or Seeds?
First, take away the food so your cat cannot eat more. Save the package or ingredient list. Estimate how much is missing and when your cat ate it. Then call your veterinarian, an emergency clinic, ASPCA Animal Poison Control, or Pet Poison Helpline if the food included fruit pits, macadamia nuts, chocolate, raisins, xylitol, garlic, onion, heavy salt, mold, alcohol, or unknown ingredients.
Do not induce vomiting unless a veterinarian or poison-control specialist tells you to. Do not give oil, milk, bread, salt water, hydrogen peroxide, or laxatives as home treatment. These can cause new problems and may delay proper care.
Emergency Signs to Watch For
Get urgent veterinary help if your cat has repeated vomiting, diarrhea, drooling, tremors, weakness, wobbliness, collapse, seizures, trouble breathing, choking, a swollen or painful belly, refusal to eat, severe lethargy, or abnormal behavior after eating nuts, seeds, pits, or snack mix.
Also call promptly if a kitten, senior cat, diabetic cat, overweight cat, or cat with pancreatitis, kidney disease, heart disease, or a prescription diet ate a fatty or unknown snack. Those cats may have less room for dietary mistakes.
Better Treat Choices
Use treats made for cats and keep them small. Treats should be occasional extras, not a major calorie source. Plain cooked meat with no bones, skin, seasoning, onion, garlic, or sauce can be a better occasional option for many cats, but ask your veterinarian if your cat has a medical condition or prescription diet.

Bottom Line
Cats should not rely on nuts and seeds for nutrition. Avoid fruit pits and seeds, macadamia nuts, moldy nuts, shells, salted snacks, seasoned mixes, chocolate, raisins, and xylitol-containing products.
If your cat ate a risky nut, seed, fruit pit, or snack mix, check the ingredients and call your veterinarian or pet poison control. Fast advice is safer than waiting for symptoms to appear.
