Mine wake up around 8pm. Eat, (sometimes crawl back into their pouch for a 1/2 hour or so), usually come back out on play with me for a couple of hours. I usually go to bed around 11. I wake up at 6am and can usually hear them playing until I get in the shower around 7am. By 7;30 when I am ready for work they are all bedded down.
Sometimes on the weekend they get up in the middle of the day and wander around. Maybe they do that during the week also but I am not here to see it. It's kinda funny though when they do that. They look drugged. Just like the way my boys looked for about 24 hours after they were neutered.
