Like many of the world's greatest love stories, this one was written by quill - two porcupines worth of them, to be exact.
A few weeks back, keepers at the Ramat Gan Safari Park in Israel noticed something out of the ordinary. For several days in a row, porcupine droppings had appeared outside the enclosure of the facility's resident porcupine, a female named Dorit who had been taken in eight years earlier as a helpless orphan.
Officials originally suspected that cleanup staff had been cutting corners by sweeping Dorit's waste beyond the fence. But, as the zoo writes on Facebook, workers denied responsibility for the errant poop.
Day after day, as the droppings continued to appear, the mystery deepened. Then another befuddling clue turned up near Dorit's enclosure - a quill.
