The bigger dogs sleep downstairs and the smaller dog sleeps with the kids. All lights turn off after pets have had their water and meals. Fish tank light is also turned off at night to help them rest. Once, all pets are in their beds, I head upstairs to my room to sleep.
It's better if they are use too big spaces or going outside. Sometimes I don't even see the cats around, but they are older now, so start letting them outside gradually and make sure you have closed gates an no small spaces under gates or fences.
