Cat litter
I’ve found it easier and much less gross when changing cat litter to have 2 litter trays. I only use one at a time with the clumping litter from Aldi (or wherever it’s on special), and instead of scooping out the gross bits I scoop out the clean dry litter and tip into a clean tray. It’s easier, quicker, more hygienic and I think the litter goes further this way.
