Why limited
Keep raw fish to small, occasional amounts. Sensitive pets may react to it, and sugar- or fat-heavy foods raise the risk of obesity and pancreatitis.
Raw fish may contain parasites (e.g., Anisakis) and thiaminase, an enzyme that destroys thiamine, which can lead to neurological signs in cats and dogs. Feeding raw fish should be limited, and the fish should be frozen to kill parasites. Observe for vomiting, lethargy, or seizures after consumption.
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
Raw animal protein carries Salmonella and E. coli risk, and those bacteria can spread to the people in the household too.
