Convenient, Good for the Environment, Economical
I love this. It clumps extremely well if the litter's deep enough (maybe around 8cm), forming a convenient ball. If the litter's too shallow it spreads out and is less of a ball, but is still easy to scoop. I hold a plastic tray under the scoop when carrying to the toilet in case of spills. Litter gets scattered on the carpet around the tray, but not tracked too badly.
