H5N1 guidance sharpens for cats, dogs, and veterinary teams

Companion animals are now a clearer part of the H5N1 conversation, as veterinary and public health agencies sharpen guidance for cats, dogs, and the people caring for them. Recent federal and professional guidance emphasizes that cats appear especially susceptible, with documented infections tied to predation, contact with infected birds or cattle environments, and consumption of raw milk or raw pet food. AVMA reporting adds that USDA has documented nearly 70 domestic cat infections this year and around 200 U.S. cat cases since the virus appeared in late 2021, underscoring that this is no longer a rare or theoretical concern in small-animal practice. FDA has also told covered cat and dog food manufacturers using uncooked or unpasteurized poultry or cattle ingredients to reanalyze their food safety plans for H5N1, reflecting a shift from theoretical risk to an active food-safety concern.

Why it matters: For veterinary professionals, the practical message is to raise suspicion for H5N1 in cats with neurologic or respiratory signs plus relevant exposure history, use PPE when handling suspected cases, and coordinate testing through state animal health or public health channels and NAHLN laboratories. The advice to pet parents is also becoming more specific: keep cats indoors, prevent access to wild birds and livestock environments, and avoid raw diets, including unpasteurized milk and commercially produced raw pet foods. AVMA coverage also highlights a practical counseling point for clinics: contaminated raw diets may remain risky for long periods when frozen or refrigerated, so exposure history should include stored products, not just recently purchased food. CDC continues to characterize the public risk as low overall, but says people with close, unprotected exposure to infected animals or contaminated environments face higher risk. (aaha.org)

What to watch: Expect continued updates on testing guidance, raw pet food oversight, and case investigations as agencies track spillover in cats and other mammals. One broader lesson from veterinary One Health reporting is that animal-associated pathogens can spread not only through direct contact but also through contaminated environments, which may shape future messaging for clinics and pet owners as H5N1 guidance evolves.
