SAN FRANCISCO, California (Reuters) -- California may become the only U.S. state to require the sterilization of pets under a bill passed by the state Assembly, pitting dog and cat lovers against animal rights activists. "It's a horrific bill," said Maureen Hill-Hauch, executive director of Castleton, New York-based American Dog Owners Association, adding that enforcement of the bill in theory could wipe out California's dog population.
