Heidi has more than 100,000 friends on Facebook. There's a Youtube song about her and she's a celebrity in Leipzig, Germany!
Heidi is a cross-eyed opossum. She was born in the USA and lives at the Leipzig zoo where she is a popular attraction.
Vets say that her eye problem causes her no pain. They think that it was either caused by a poor diet or from fatty deposits, behind the eyeballs, forcing them to cross.
A stuffed animal "Heidi" goes on sale soon... too late for the holidays... damn!
