This is one reason we went ahead and bought Mr. Waya. Chuhga was running me ragged. Now they run each other ragged. LOL She slowed down while she was pregnant and after she had the puppies, she was just too pooped to play. Now she is at it again. When they go outside (we have a big fenced in yard) they run like the devil is behind them. The poor cats have to get up high to get any relief.
