Peanuts
Peanuts
Plain, unsalted peanuts are not toxic to cats, but they are an inappropriate snack for several reasons. Peanuts are very high in fat, which can trigger pancreatitis with regular feeding. They also carry a risk of aflatoxin contamination (a toxic mould byproduct) and offer no nutritional benefit to obligate carnivores.
Important Notes
Not acutely toxic: plain peanuts do not contain cat-specific toxins
Fat risk: very high fat content; regular feeding can cause pancreatitis (painful, potentially fatal pancreatic inflammation)
Aflatoxin risk: mouldy or improperly stored peanuts may contain aflatoxins, which cause liver damage
Salted, flavoured, or roasted peanuts: high sodium and artificial seasonings are harmful to cats
Peanut butter: most brands contain xylitol or excessive salt — check labels; a tiny taste of plain peanut butter is unlikely to cause harm

Possible Symptoms Reported in Cats
Aflatoxicosis (From Moldy Peanuts)
Gastrointestinal · Acute (shortly after a large dose) or chronic (developing progressively over time with low-dose expo
Hypoglycemia and Liver Failure (From Xylitol in Peanut Butter)
Gastrointestinal · 15 to 30 minutes for hypoglycemia (or delayed up to 12 hours depending on the product);
Sodium Ion Poisoning (From Salted Peanuts)
Neurological · Within minutes to hours of ingestion
Severe Allergic Reaction
Respiratory · Immediate to a few hours.
Indigestion and Pancreatitis (From High Fat Content)
