Are leos less active as they grow older?

This is my guy, Harry. He's been with me since 2018. For the past two years, he's grown increasingly inactive. Whenever I take him out of his enclosure he either

  1. Stays on my shoulder

Or

  1. Hangs out on that alarm clock.

Like, he can literally stay on me or the clock for hours. He doesn't do much in his enclosure. There's plenty of space for him to crawl in or under. It's just nothing.

Any advice or insight?
