Why limited
Keep Cooked liver to small, occasional amounts. Sensitive pets may react to it, and sugar- or fat-heavy foods raise the risk of obesity and pancreatitis.
A tiny amount of cooked liver is fine, but liver is extremely high in vitamin A — regular feeding causes vitamin A poisoning (bone problems).
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
Cooked bones splinter rather than crumbling, and fragments can lodge in the throat, stomach or bowel, sometimes needing surgery to remove.
