Seven years ago, there were no nonnative squirrels on the UC Davis campus. But because the lusty little beasts have been getting' busy, there are now 400 of them running around sampling student lunches, eating baby birds, and snacking on electrical wires. That's why scientists at UC Davis are test-driving squirrel birth control. Students and faculty are catching the horny little rodents, injecting them with hormones, and releasing them back into the wild where they will "continue to do as squirrels do." Pshaw! I say try abstinence programs first before taking such drastic measures! (Click here if you're not persuaded by my suggestion.)
