Saskatchewan Cat Dies From Avian Flu

A domestic cat in southeastern Saskatchewan has died after contracting the H5N1 strain of highly pathogenic avian influenza. The case, confirmed by the Canadian Food Inspection Agency and Prairie Diagnostic Services, highlights the ongoing risk of the virus jumping from wild birds to mammalian pets.

According to a news release from the provincial Ministry of Agriculture, the cat appeared normal on the morning of April 20, 2026. However, the animal’s health deteriorated rapidly, and it died later that same day.

The provincial government reported that the cat became suddenly, severely ill with sudden neurological and respiratory signs before its death.

The cat was known to spend time outdoors, a factor that increases the likelihood of exposure to the virus. Health officials noted that the risk of exposure is typically higher during spring migration, a period characterized by increased wild waterfowl activity.

While the risk of transmission to humans is considered low, virologists are closely monitoring the virus’s ability to infect mammals. Bryce Warner, a research scientist at the Vaccine and Infectious Disease Organization (VIDO) at the University of Saskatchewan, noted the specific concerns regarding mammalian adaptation.

In response to the infection, the province is reminding pet owners to implement safety measures to protect their animals during the spring season. These precautions include keeping cats indoors and ensuring that dogs are kept on leashes.

The Canadian Food Inspection Agency has indicated that various mammalian pets, including dogs and cats, are at risk of contracting the illness. Because the virus can manifest in several ways, owners are encouraged to be vigilant for specific warning signs.

Symptoms of highly pathogenic avian influenza in pets may include:

• Lack of appetite
• Loss of coordination
• Difficulty breathing
• Neurological signs, including seizures and tremors

The provincial government further cautioned that sudden, unexplained death is also a possible symptom of the infection.

Testing conducted at Prairie Diagnostic Services in Saskatoon confirmed the presence of the HPAI strain in this case. While the specific location of the animal’s residence was not disclosed, the event has prompted veterinary officials to maintain vigilance for further cases in the region.
