Tired of spilling cat sand on the floor when cleaning the cat box I though of an idea. What if I didn't need to insert the scoop into a plastic bag, what if the plastic bag was part of the scoop. I designed this which is now in it's second version but still in development.
I recommend printing as smooth as possible to make cleaning easier.
To use just hold a plastic bag over the tubular end. With a quick flick of the wrist the litter goes into the plastic bag, no spill and no mess and all sand stays in the box.
