My cats love the storage bin litter box as much as I do! Penelopy just loves to dig dig dig dig in there. I hear her digging all night long :lol3: Not necessarily DOING anything, just digging. And yes, MUCH less getting kicked onto the floor! Reminds me, I need to schlep the 40lb bag of litter to my bedroom and top it off tomorrow.i was just saying (above) that i'd just finished making the 3rd and 4th of our plastic storage bin litter boxes! i ordered my 22 gallon bins from walmart, site to store. i bought a 6 count package of them, at a great price. i use inexpensive litter pans inside them, and have extra pans so i can easily switch them out when doing a complete change/wash out of the litter boxes. i'm finding that it's so easy to do the daily scooping now, and so much less litter is getting kicked out onto the floors too!
