CNN is reporting that Australia might put their kangaroos on the pill to keep numbers down. Apparently, the kanga population around the nation's capital has skyrocketed in recent years. In fact, Canberra finds the creatures especially problematic during dry spells, because they bounce over from the outskirts to snack on the city's manicured lawns and golf courses. And while other means of curbing the population have been explored (particularly vasectomies for male roos, and injections for females), capturing the marsupials (to actually do the altering) is sort of a tricky and dangerous business. Instead, scientists are developing oral contraceptive pills that double as "irresistible treats" and plan on hiding them all across the countryside. The kangaroo pill should be out within  2-5 years, and some of the more vocal animal rights groups are applauding the option as humane. Kangaroos, on the other hand, have yet to speak out on the matter.
