Why limited
Keep Peanut butter to small, occasional amounts. Sensitive pets may react to it, and sugar- or fat-heavy foods raise the risk of obesity and pancreatitis.
Safe only if xylitol-free (many brands now add it — xylitol is fatal to dogs). High fat and salt — small amounts.
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
Even a gram or two of xylitol can trigger a sharp drop in a dog's blood sugar, and larger exposures go on to damage the liver.
A heavy salt load drives up thirst and urination, and in the worst cases leads to sodium ion poisoning, which is a genuine emergency.
Added sugar brings empty calories, and over months that means weight gain and dental disease — both far harder to undo than to avoid.
Rich, fatty food is the classic trigger for pancreatitis, a painful inflammation of the pancreas that usually needs veterinary treatment rather than rest alone.
