San Mateo County District Attorney Steve Wagstaffe says when 26-year-old Yevgeniy Bolshakov of Daly City came home from an outing Saturday, he asked his parents about the cat.
When they told him it was recovering from surgery and that he couldn't see the animal, Wagstaffe says, Bolshakov punched his 64-year-old father in the head, biting the older man on the arm and ripping off a piece of flesh, before biting and punching his mother.
Bolshakov pleaded not guilty Monday to charges of assault, mayhem and making criminal threats.
The San Francisco Chronicle reports Bolshakov is in county jail in lieu of $100,000 bail.
