The clocks go one hour ahead this weekend so that's one less hour with the hammies at night although all my hammies were surprisingly up around 7pm, all their wheels were going at once. Their sleep schedules fluctuate but generally they are all up by 9:00pm, soon to be 10:00pm
I'll hopefully catch up with them in the morning hours after time zone change? I'm sure the hammies don't have their own little clocks that fluctuate
