Bird flu causes deaths of cats and zoo animals as virus spreads in US

Just days after the USDA issued a new order that all raw milk must be tested for bird flu, reports have emerged of animals dying of the virus, including cats and several zoo animals.

After drinking the milk, the felines displayed symptoms that included lack of appetite, fever and neurologic issues, according to a press release from the Los Angeles County Department of Public Health. "We are all devastated by the loss of five cherished animals." "Studies indicate that even a single mutation could significantly enhance its infectivity in humans."

"The infected cats died after severe worsening of their illness, and subsequently tested positive for influenza A, a rare result in cats," the release stated.
