Astra doesn't have a good bladder so she sometimes comes and wakes us up at 3 or earlier. Sometimes she waits for my parents to let her out when they get up at 5. Molly stays asleep until I get up at 6 and that is when I let her out. Prince is a sleepy head and waits until around 7:30 to be let out. We let them out at that time right before we leave for school. Molly can hold her pee for a long time too. When she was spayed she didn't go the entire time she was at the vets so when she got home she peed for a good few minutes.
