Mine have a routine as well, though I am not a person of habit, so I am not that strict with mine, much to their displeasure. lol They have their own room, which they are loath to leave until about 5pm so that is when they get let out (do not disturb their sleep or you shall paaaay!), then they do running around / binkies / eat their floor hay (I keep a pile of hay in the living room floor for them, else they eat the carpet and it apparently tastes SO much better than the hay in their room even though it’s often taken from their hay box). Then they get their salad around 7 and then it’s flop out time til around 8, then it’s run around zoomie time. At 9:30ish they get dinner and put back in their room for bedtime and Powder grooms Stickers (though she won’t return the favor). On the weekends they get to stay up later and they love it and do lots of extra binkies to show their pleasure at humans staying up past midnight.
During the night / early in the morning they play in their room, but not sure exactly how active they are or for how long, I am not a morning person – I can hear their little paper tunnels and stuff crinkling though.
