I have found with 5 and 1 vole, I have no spare time anymore
They are all late risers and so I have become a night owl! They all get 20/30 minutes ball time and handling too, if they want to. I am finding Kretchers doesn't want to come out every night now. Bonaparte is desperate to get out always and then caves in and wants to go back, Desi sometimes does, sometimes doesn't and Algy wakes up late but then wants to be out all evening.
But in short, I no longer have any hamster free time, but wouldn't be without them.
