Lola and Shirley are out now having a good scamper around, they've been out for about half an hour or so. They tend to be very active all night, from 8/9ish to the small hours. My boys both live on their own, and aren't so active, but come out a bit later and run in their wheels.
All of them also come out a few times during the day for a drink and a bite to eat, i'll often see a movement out of the corner of my eye, it'll be one of the robos having a spot of lunch or something. If it's Merry I can feed him a treat through the cage bars when I see him
(hmm.....maybe
that's why he got so much fatter than the others!)
