In the newly-clean rodent motel there are a Graze box insert and some loo roll tubes for them to demolish, and top left you can see the industrial-pink-coloured mineral chew block I got them. Not visible because it's buried: a hollow half-log that they immediately adopted as their new clubhouse.

After slobbing all weekend (well, I went out to museum & cinema yesterday, but otherwise in bed feeling coldy), today I've done a bunch of washing up and cleaned out the gerbil cage. Even shifted their normal chest of drawers to roomba underneath. I'm almost an adult!
