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.

Why these cautions matter
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.
Raw animal protein carries Salmonella and E. coli risk, and those bacteria can spread to the people in the household too.
