It's really interesting to watch this progression, and see that Mazy cat has learned to PACE HERSELF!
When she first started playing again she was so happy, so THRILLED, to be able to move and play without pain that I was afraid she would over do and be sore the next day, so I would limit the session to only a few minutes.
However watching her carefully I see she has learned her limits, she will play as long as she feels is right, then stop. She was skipping nights, playing every other night, or every second night, I mean for a few weeks.
Mostly she plays every night now, but I do notice on a night when she has thundered around the house and/or been airborne a lot, the next night she will only play quiet Games that don't involve a lot of moving.
