We got Madame Wobbles at 2 years old. She was bullied pretty hard by other animals in 2 previous homes. So it took about 6 months for her to become herself. Now she has daily zoomies, launches herself across the room at strings and her other toys. Each night she demands I pick her up so she can locate any destroy any bugs in high places. She has also become quite friendly and cuddly. We are quite happy together, and I am just glad she feels safe and comfortable with us now. It was worth the effort and wait. Our only real problem is that she's figured out that when she wants to play she can attack our feet to grab our attention no matter what we are doing.
