Three of my bunnies play race cars.....they start in the kitchen come tearing out into the living room, through their tunnel, back to the far side of the living room, through a litter box and then on to the finish line back in the kitchen. They also like to play shot put and are trying for a long distance record. The Dig-to-China game is also a favorite...their telephone book is down to Contractors in the yellow pages.
Their absolute favorite thing to do however is not really a game. They like to remodel their living quarters. Daisy has taken down a wall in her castle (fortunately it was not a load-bearing wall), made the first floor west window into another door and put in a picture window on the second level. She also decided she didn't like the flooring in her tunnel and has replaced it with hardwood flooring. Then there is the Persian Rug game, but we won't get into that one........
