Heidi, the cross-eyed opossum at a German zoo who became an internet sensation (winning three times more Facebook admirers than German Chancellor Angela Merkel) is dead, her zoo said today. She was euthanized to avoid suffering pain from severe arthrosis, a degenerative joint disease. She was three-and-a-half years old.
Auf Wiedersehen, Heidi. Miss you already, pretty girl.
