Imagine your curious feline giving you those big, expectant eyes while you’re slicing up fresh sashimi. It might seem harmless—after all, it’s just thinly-sliced raw fish.
Cats should not eat sashimi. While a tiny bite may seem harmless, raw fish can carry parasites and destroy vital nutrients like thiamine. Always serve cooked fish instead to keep your cat safe and healthy.
In this article, we’ll walk you through what sashimi actually is, the real dangers and benefits for cats, and how you can offer safe alternatives that let your whiskered friend taste the sea—without the worry.
What sashimi actually is—and why sourcing matters
Sashimi-grade fish used by reputable restaurants and fishmongers is typically handled under stricter cold-chain controls and, for many species, frozen to kill parasites before serving. That said, “sashimi grade” isn’t a standardized legal term, and safety still depends on correct time/temperature controls, species, and origin. Even when parasite risks are reduced, raw fish can still harbor bacteria like Salmonella or Listeria, which is why public health guidance emphasizes cooking fish to safe internal temperatures for people—and by extension, why raw fish isn’t ideal for pets.
The real risks: parasites, bacteria, and foodborne illness
Raw fish can carry parasitic worms (e.g., Anisakis) that embed in the flesh. Human food codes require restaurants that serve raw fish to use parasite-destruction freezing steps precisely to address this hazard. Pets are susceptible to many of the same organisms, and cats—who groom and roam around shared household spaces—can turn a kitchen “tasting session” into a hygiene problem for everyone if raw juices contaminate counters and bowls. Public agencies repeatedly underline that proper cooking or validated freezing is needed to control parasites; otherwise, illness can result.
What “sushi-grade” freezing actually means
Food codes based on federal guidance specify parasite-killing options before serving fish raw, such as:
- −4°F (−20°C) for 7 days; or
- −31°F (−35°C) until solid and held at −31°F (−35°C) for 15 hours; or
- −31°F (−35°C) until solid and then held at −4°F (−20°C) for 24 hours.
These controls reduce—but don’t erase—risk, and they don’t address every hazard (for example, certain bacteria). Moreover, effectiveness varies by species, parasite, and process control. Home freezers generally can’t achieve or verify these specific commercial parameters.
A nutrition trap: thiaminase in raw fish
Many raw fish species contain thiaminase, an enzyme that destroys thiamine (vitamin B1). Cats have high thiamine needs; chronic intake of thiaminase-rich raw fish can lead to thiamine deficiency, causing neurological signs (incoordination, seizures), appetite loss, and even coma if untreated. Cooking inactivates thiaminase, which is one reason raw fish isn’t recommended as a steady treat. Veterinary sources specifically caution that an all-raw-fish approach is a recipe for deficiency.
Mercury and species matters (especially tuna)
Predatory species like tuna accumulate more mercury than small, short-lived fish. While the exact “safe amount” for cats depends on body weight and overall diet, routine tuna treats—raw or cooked—can push exposure upward over time. For this reason, fish (especially large pelagic species) should be an occasional accent rather than a daily staple, and complete cat foods should provide the bulk of nutrition. (Veterinary and public-health guidance consistently prioritizes balanced, complete diets over frequent single-ingredient treats.)
Why major veterinary organizations caution against raw diets
Veterinary and public-health bodies have repeatedly advised against feeding raw animal proteins to pets, citing pathogen risks to animals and people in the household, including children or immunocompromised individuals.
Even with careful sourcing, raw foods can expose pets and humans to Salmonella, E. coli, Listeria, and parasites. The safest approach is to feed nutritionally complete commercial cat food (which is formulated to meet recognized nutrient profiles) and limit human-food treats.
If you still plan a one-time taste, keep these guardrails
If you and your veterinarian decide a tiny one-off taste is acceptable for a healthy adult cat (not for kittens, pregnant cats, seniors, or immunocompromised pets), follow strict precautions:
- Choose fish from a reputable source that follows parasite-destruction freezing for raw service; avoid freshwater fish (more parasite risk) and high-mercury species. Food codes require operators to document parasite-destruction steps for raw fish.
- Offer a minuscule amount (a pea-sized sliver), no more than occasionally, and watch for vomiting, diarrhea, lethargy, or neurologic signs afterward. If symptoms occur, contact your vet promptly. Public-health guidance advises seeking medical care after suspected raw-fish foodborne illness; the same vigilance applies to pets.
- No sauces or seasonings. Soy sauce is salty; wasabi and pickled ginger are irritants; scallions/garlic are hazardous to cats. The ASPCA lists common human foods and additives that can be unsafe for pets.
- Kitchen hygiene matters. Wash hands, utensils, and surfaces thoroughly after handling raw fish to protect both pets and people. This is standard infection-control practice emphasized by veterinary and public-health guidance.
Even with these measures, the safest plan is not to feed raw fish to cats.
Far safer ways to give your cat that “fishy” experience
If your goal is to delight your cat with fish flavor without the microbial and nutritional risks of sashimi, try these safer alternatives:
- Cooked, plain fish bits (boneless, skinless, baked/poached to doneness, cooled, no salt): Cooking achieves the temperature needed to kill parasites and reduce bacteria. Keep portions tiny and occasional.
- Commercial cat treats or foods that feature fish as an ingredient and are formulated to meet recognized nutrient profiles for complete and balanced feline diets. Taurine, thiamine, and other critical nutrients are built in to meet standards.
- Prescription or vet-recommended diets for cats with health conditions (e.g., weight management, urinary health) that still deliver palatability without compromising safety. University veterinary centers highlight balanced nutrition as a cornerstone of feline health.
What to do if your cat already ate sashimi
Most healthy cats that sneak a tiny piece may be fine, but watch closely for 24–72 hours. Call your veterinarian if you notice:
- Vomiting, diarrhea, or refusal to eat
- Lethargy or fever
- Abdominal discomfort
- Neurologic changes (wobbliness, twitching)—which can indicate thiamine issues if raw fish is a frequent habit
If your cat is very young, elderly, pregnant, has a chronic illness, or is immunocompromised, err on the side of calling your vet even if no symptoms appear. Raw fish can transmit pathogens that are particularly risky for vulnerable individuals. Public guidance emphasizes cooking to 145°F to ensure safety; if raw fish was ingested and symptoms follow, seek professional care.

Conclusion
Cats may love the smell and taste of fish, but sashimi is not a safe choice for them. Raw fish, including sashimi and sushi, can contain parasites, bacteria, and an enzyme called thiaminase that harms your cat’s health. Even a small piece can lead to stomach issues or vitamin deficiencies over time.
If you want to give your feline friend a special treat, always choose plain, fully cooked fish without salt, oil, or seasonings. Cooked salmon or white fish in small amounts is a much safer option.
Your cat’s health and happiness come from a balanced, complete diet, not from risky raw fish snacks. When in doubt, talk to your veterinarian before introducing any new food — keeping your kitty safe is always worth it.
