This is precisely why you don’t try to pry a dead mouse from the jaws of a stray cat. An Oregon man has been diagnosed with the plague after he was bitten by a stray cat that his family knew and had befriended. The man, in his 50s, is in critical condition, while the cat, which officials say probably has the plague, is being tested by the CDC. How rare is the plague in Oregon? It’s the fifth case since 1995.
