Is Bobbie deaf by chance? If not, maybe it's time to get him all fired up with an interactive play time every night before you go to bed. Cat Dancers are terrific for tiring out cats, as are feather wands, and laser pointers. Be very careful not to point the beam into eyes! Turbo Scratchers are toys that they expend a lot of energy with as well, but remove the ball from the track and put it in a drawer before going to bed! Otherwise you'll hear that annoying whizz of the ball all night long.
