Bird flu has been on the rise in Washington state and one sanctuary was hit hard: 20 big cats – more than half of the facility’s population – died over the course of weeks.

Following one pet fatality, Oregon health officials have traced the cat’s illness to frozen cat food that contained raw turkey.

A backyard flock in Vermont was sickened with H5N1, agricultural officials said on Thursday, following other reports of bird flu-related animal deaths this month beyond commercial farms and wildlife.
