UNSAFE
Feeding Cats Raw Fish

Feeding raw fish to cats is unsafe due to risks of thiamine deficiency, parasites, and bacterial infections.

Critical Warnings

Raw fish contains thiaminase, an enzyme that destroys thiamine (vitamin B1), potentially causing severe deficiency and neurological issues. Parasites like flukes in raw fish can infect cats, leading to liver damage or other complications. Bacterial contamination, such as Salmonella, increases the risk of foodborne illnesses. Cook fish thoroughly or use balanced commercial cat food to avoid these dangers.

The Science

Cats may love fish, but raw fish is hazardous. The thiaminase enzyme in fish like salmon, herring, and tuna inactivates thiamine, leading to deficiency symptoms including lethargy, poor appetite, seizures, and heart failure if fed regularly. Raw fish also carries risks of parasites (e.g., Heterophyes heterophyes) and pathogens like Listeria or Vibrio, which can cause gastrointestinal upset or systemic infections. Veterinary guidelines from organizations like the AVMA advise against raw diets due to these imbalances and contamination risks. Opt for cooked fish as an occasional treat or rely on AAFCO-approved cat foods for complete nutrition.
