Click here for information about the Avian Flu


Avian Influenza, also called H5N1, is a viral disease found in wild and domestic birds. It is transmissible to many mammals, with our biggest concern being pet cats. The most likely ways for cats to become ill is by catching wild birds or from eating a raw-food diet. People can also become sick from avian influenza.

There have been several recent cases of cats contracting avian influenza (and dying) from being fed a commercial frozen raw-food diet. Transmission is also possible from feeding raw (non-pasteurized) milk. Freeze-dried or high-pressure pasteurized diets have a lower risk of causing avian influenza but still have a potential to transmit pathogens. If you are currently feeding a raw diet, we recommend transitioning your pet to a cooked diet. Frozen raw diets can be baked before feeding to kill the virus. 

Cats can also become infected with avian influenza from hunting wild birds. We recommend keeping cats inside at all times, or allowing them outside only while monitored on leash or contained in a catio or cat tent.

Symptoms of avian influenza in cats include respiratory signs such as nasal discharge, coughing and wheezing, and neurologic signs such as wobbliness, difficulty walking and seizures. If you are concerned your cat could be exhibiting signs of avian influenza either call us or your local emergency clinic. Keep in mind that avian influenza is relatively rare, and there are many other diseases that can cause similar signs. If your cat is not allowed outside and is not eating a raw diet then your cat does not likely have avian influenza. If your cat is having trouble breathing or is not able to stand, head to the nearest emergency clinic right away, calling them while en route. 

There is no vaccine to prevent avian influenza in cats.

WE HAVE THE MEDGENE™ RABBIT HEMMORHAGIC DISEASE (RHDV2) VACCINE! We are on a mission to get as many rabbits vaccinated as soon as possible and have started offering this vaccine during special vaccine clinic days. Our first special rabbit vaccine clinic day was a huge success (and super fun to get to see some many bunnies in one day), and we vaccinated 22 bunnies! We will be setting up more of these special vaccine clinic days, and hope to eventually be able to offer the vaccine on a regular basis.

In case you don’t already know, rabbit hemorrhagic disease is a highly contagious, fatal disease in rabbits and is currently classified as a reportable, foreign animal disease in the United States. Animal health officials detected rabbit hemorrhagic disease virus serotype 2 (RHDV2) for the third time in the United States in February 2020. It has since been spreading to multiple states across the Southwest. RHDV2, unlike other rabbit hemorrhagic disease viruses, affects both domestic and wild rabbits. Infected rabbits may develop a fever, be hesitant to eat, or show respiratory or nervous signs. However, many times, the only signs of the disease are sudden death.
RHDV2 can be spread through direct contact or exposure to an infected rabbit’s excretions or blood. The virus can also survive and be spread from carcasses, food, water, and any contaminated materials. It has also been spread by insects. Because of survivability, people can spread the virus indirectly by carrying it on their clothing and shoes after being exposed to an infected animal or environment. All bad news for our bunny friends!

If your rabbit is an established patient and has had an annual wellness exam by a NSVC Veterinarian in the last 12 months, please keep your eye out for emails that will be sent out as the vaccine clinics become available.
