A wildlife sanctuary in Washington announced it is going into quarantine until further notice after 20 big cats died due to bird flu infections.

The Wild Felid Advocacy Center in Shelton, Washington, reported that 20 of its large cats, including a half-Bengal tiger and four cougars, died between late November and mid-December after contracting an unknown illness, which later was identified as H5N1 avian influenza, or bird flu.
