What happens if my 5 kg cat eats a few bites of plain sushi rice from my takeout every single day?

Short answer

Feeding sushi rice daily is not recommended. While the plain rice itself isn't toxic, a regular diet of it can lead to weight gain and nutritional imbalance because it's high in carbohydrates and lacks the protein and taurine cats need. Over weeks or months, this can contribute to obesity and related health issues like diabetes. It's much safer to keep human food as a very rare treat and stick to a balanced, complete cat food as their main diet.

Sushi — Food safety facts

Feed with care · Cats · full breakdown on the linked food page

Rice is fine, but wasabi, pickled ginger and raw fish are not.

Dogs and cats carry the same rating (Feed with care), so the notes below hold for either pet.

Sushi is not poisonous to cats, but it is easy to over-feed. Rich fat, salt or seasoning can bring on vomiting or diarrhoea within a day, and repeated large portions are a recognised trigger for pancreatitis.

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.
