We have 5 that love to tear around the house, occasionally jump on toes and don't have much time for loves and hugs when its play time!
However, if a playful companion is not an option, we did learn a few tips when our first cat Roady had to make a quick transition from outdoor kitty to indoor kitty. She was driving us nuts with her pent up energy and at all hours. We basically got the most interesting feather toys & a thing called a catdancer to play with her & made sure she had a 30 min session before bedtime. A great organization called Wisconsin Cat Club told us that if a kitty has a 20-30 minute play session before bed, they would soon learn to sleep most of the night. And I mean we played hard - but never wrestling with her with our hands (she had the potential to be a play biter and we didn't want her to think we were fair game). We dragged feather toys through the house, up on the bed, down and then back up, tossed catnip mice up the stairs for her to chase and bring back, made her play up on the cat scratcher tree with a feather...you get the idea. We tired her out and within 3 days she was no longer getting us up at night and seemed calmer during the days.
We still play feather toy with the 5 guys we have now, but they also do a tremendous amount of cat wrestling, chasing and goosing with each other and the dog.
One other thing and then I'll shut up....if you do get a companion, try to make sure its personality is going to be playful, crazy cat too! Nothing worse than having a high energy cat trying to get a low energy couch potato to play with him.
