Why limited
Keep Sugar to small, occasional amounts. Sensitive pets may react to it, and sugar- or fat-heavy foods raise the risk of obesity and pancreatitis.
No nutritional value and it feeds obesity and dental disease. Not toxic, just pointless.
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.

How often can cats have Sugar?
Save Sugar for rare moments rather than building it into a routine; your cat may enjoy it, but that alone does not make it fit to feed often.
