More than a century's worth of matrimony wasn't enough to keep them together. After 115 years as an item, two tortoises at an Austrian zoo have decided to call it quits. Trouble began recently when Bibi and Poldi started to pester one another in the cage they've shared at the Klagenfurt Austrian Zoo, where they've resided for 36 years. The two hulking creatures grew up together and, until now, have been inseparable. But now, the star-crossed tortoises refuse to share a cage with one another. "We get the feeling they can't stand the sight of each other anymore," Zoo Director Helga Happ told Austrian Times.
