I’ve said it before, and I’ll say it again: this is why I looooove the 'Dope.
Such a sensible solution!
You are sweet to do this, but one quibble - I think “XL Tall” is a more popular size than you think. 
Anyway, good luck with de-cluttering. (We have a thread for that!)
I’m up having a toaster strudel snack but will be re-joining the cats in bed shortly. The ratties all got a biiiig meal of birdseed mix last night, and I can hear them still sorting through the good stuff, and more “Week! Weeeek!” pups squealing.
There are more litters than I thought!
I’ve been slacking on the endless setup-move-dump-clean cycle of keeping them on fresh bedding (pro tip: have at least one more tub than groups needing an enclosure) and I really need to get my butt in gear on that, especially if they’re having Teh Bebbies.
Which surprises me, they normally dial their breeding way back in winter.
Quarantine boredom strikes us all, eh?
