I've got kitty buckets.
I've got other buckets / bins / etc too.
I just... this is kinda meant for a bit longer storage. So it's going into boxes.
Although - I had ahold of a full styrofoam trays by one side and it snapped in half. I'll admit to nearly losing my temper

Otherwise, so far I'm fine with the boxes. They seem to scratch and OCD itch (or something).
