Many people think wild rabbits hopping around are adorable—there's even an international rabbit day celebrating wild and domestic rabbits—but they're less welcome when they're eating your carefully tended garden. Wild rabbits in California can devour your garden vegetables, just like Peter Cottontail. And they don't stop at lettuce and beans. Rabbits and hares will gnaw tree bark, flowers, most green vegetation, and even drip irrigation tubing.
