🐾 Vet’s Guide to Bird Flu (H5N1) in Cats: Symptoms, Treatment & Prevention in 2025 🐾

By Dr Duncan Houston BVSc

Bird flu, or avian influenza (H5N1), is a viral infection primarily affecting birds but has been known to infect mammals, including cats. While rare, recent cases have highlighted the importance of awareness and prevention. This guide provides comprehensive information on bird flu in cats, tailored for Australian cat owners in 2025.

🔬 Understanding Bird Flu (H5N1) in Cats

H5N1 is a subtype of the influenza A virus, commonly found in wild birds. Transmission to cats can occur through:

• 🐾 Ingesting infected birds: Cats that hunt or scavenge infected birds are at risk.
• 🐾 Consuming contaminated raw poultry or eggs: Feeding raw diets can expose cats to the virus.
• 🐾 Contact with contaminated environments: Areas frequented by infected birds can harbor the virus.

While human-to-cat transmission is rare, it's essential to maintain good hygiene, especially if handling sick birds or poultry. ^PetMD

🦠 Symptoms of Bird Flu in Cats

Signs of H5N1 infection in cats may include:

• 🐾 Fever and lethargy
• 🐾 Loss of appetite
• 🐾 Respiratory distress (coughing, sneezing)
• 🐾 Nasal and ocular discharge
• 🐾 Neurological signs (seizures, incoordination)

These symptoms can progress rapidly, and the mortality rate is high. Immediate veterinary attention is crucial. ^PetMD

🧪 Diagnosis

Diagnosing bird flu involves:

• 🐾 Clinical evaluation: Assessing symptoms and exposure history.
• 🐾 Laboratory testing: PCR tests on nasal or throat swabs to detect viral RNA.
• 🐾 Serological tests: Detecting antibodies against H5N1.

Early diagnosis can improve the chances of supportive treatment success. ^PetMD

💊 Treatment Options

There is no specific antiviral treatment for H5N1 in cats. Management focuses on supportive care:

• 🐾 Hospitalization: For severe cases requiring intensive care.
• 🐾 Fluid therapy: To prevent dehydration.
• 🐾 Oxygen supplementation: For cats with respiratory distress.
• 🐾 Nutritional support: Ensuring adequate caloric intake.

Isolation is necessary to prevent potential spread to other animals. ^PetMD

🛡️ Prevention Strategies

Preventing bird flu in cats involves minimizing exposure:

• 🐾 Keep cats indoors: Reduces contact with infected birds.
• 🐾 Avoid raw diets: Do not feed raw poultry or eggs.
• 🐾 Practice good hygiene: Wash hands after handling birds or poultry.
• 🐾 Monitor for recalls: Stay informed about pet food recalls related to H5N1.

Currently, there is no vaccine for H5N1 in cats. Vigilance and preventive measures are the best defense. ^PetMD

📍 Considerations for Australian Cat Owners

In Australia, wild birds are prevalent, increasing the risk of exposure. Cat owners should:

• 🐾 Secure outdoor areas: Use cat enclosures to prevent hunting.
• 🐾 Supervise outdoor time: Limit unsupervised roaming.

By taking these precautions, Australian cat owners can help protect their pets from H5N1.
