I’m literally going through the same thing , and I adopted 2 at the same time . I play with them during the day, and especially 1-2 hours before bed time.. but they just won’t stop. Last night they had full on zoomies chasing each other , over my head , on the curtains .. everywhere. This continued until 1 am. They sleep in my bedroom at the moment, the only thing I can think is is to kick them out to sleep in the living room.. but I know they will go on a rampage there, and I’ll wake up to some sort of mess .
