Why limited
Keep Peanuts to small, occasional amounts. Sensitive pets may react to it, and sugar- or fat-heavy foods raise the risk of obesity and pancreatitis.
High in fat and salt, and stored peanuts can carry aflatoxin mould. Unsalted few only.
Dogs and cats carry the same rating (Feed with care), so the notes below hold for either pet.
If it ate some before you noticed, watch for vomiting, diarrhoea, loss of appetite, unusual tiredness or a painful, swollen abdomen over the next 24 hours. A one-off small amount in a healthy adult usually passes with water and rest; repeated exposure, a puppy or kitten, a senior, or a pet with an ongoing illness is a reason to call your vet the same day.

Why these cautions matter
Mouldy food can carry tremorgenic mycotoxins, which produce uncontrollable tremors and seizures rather than a simple stomach upset.
A heavy salt load drives up thirst and urination, and in the worst cases leads to sodium ion poisoning, which is a genuine emergency.
Rich, fatty food is the classic trigger for pancreatitis, a painful inflammation of the pancreas that usually needs veterinary treatment rather than rest alone.
