mine wake up anywhere between 6 (if all the lights are out) or 9 when lights are on, I'll hear them snickering now and then telling me to turn out the lights and feed them already ^-^, they eat and stay up for a couple hours, sleep again for a while and wake back up at around one and play, sometimes when hubby gets up to work at 3am they run all over the cage and steal his attention for a while ^-^
