Vomiting, diarrhoea, reduced appetite, lethargy.
Stop feeding and monitor; seek veterinary care if signs persist.
Cats tolerate fatty foods poorly, peanuts offer no required nutrition, and the choking and mould risks apply just as much.
What to do after ingestion
Vomiting, diarrhoea, abdominal pain, reduced appetite; unsteady walking or incoordination should raise suspicion of xylitol (some sugar-free peanut butters contain it, which is an emergency).
A small amount of plain unsalted peanut only needs observation; seek care for persistent vomiting or abdominal pain; go to an emergency clinic immediately if xylitol-containing peanut butter was eaten.
Aflatoxins (in mouldy peanuts)
Peanuts are about 49% fat, which can cause stomach upset and may trigger pancreatitis; mouldy peanuts can carry aflatoxins (liver toxic); whole peanuts are a choking hazard for small dogs.
