Cats often show interest in human snacks. Peanuts catch their eye sometimes. But are they safe? This guide covers the facts. It draws from vet advice and recent studies. We checked details as of September 2025. No major updates change the basics. Peanuts are not toxic. Yet they bring risks. Read on for clear answers.
Is It Safe for Cats to Eat Peanuts?
Cats can have a few plain peanuts now and then. But it’s not a good idea most times. Here’s why.
The Basics on Peanuts and Cats
Peanuts grow in pods. They count as legumes, not true nuts. People eat them for protein and fats. Cats need meat for those things. As obligate carnivores, cats get little from plants like peanuts. A small unsalted peanut won’t hurt a healthy cat. Still, keep portions tiny. One or two at most, once in a while.
Do Peanuts Offer Any Benefits?
Peanuts have protein, fats, vitamins, and minerals. These help human hearts and bones. For cats, the story differs. Their bodies break down animal proteins best. Plant fats in peanuts can upset stomachs. Vitamins like E or B in peanuts add small value. Better sources exist in cat food. No real gain here for your pet.
- Protein: About 25 grams per 100 grams of peanuts. But cats use it poorly.
- Fats: High levels, around 50 grams per 100 grams. This risks weight gain.
- Other nutrients: Fiber and minerals like magnesium. Not key for cats.
For balanced meals, stick to cat-specific options. Check our pet food safety checker for quick scans.
Risks When Cats Eat Peanuts
Peanuts seem harmless. But problems arise. Watch for these issues.
- Choking danger: Whole peanuts are hard. Cats may swallow without chewing. Shells make it worse. They can block throats or guts.
- Stomach troubles: High fats lead to vomiting or loose stools. Some cats get diarrhea right away.
- Weight problems: Extra calories build up. Obese cats face diabetes or joint pain.
- Salt issues: Salted peanuts cause thirst, shakes, or seizures. Avoid them fully.
- Allergy signs: Rare, but possible. Look for itching, swelling, or breathing trouble.
- Shell hazards: Sharp edges harm insides. Always remove shells.
If your cat has health conditions like pancreatitis, skip peanuts. Talk to a vet first. For more on cat diets, see our post on can cats eat cheese.
