Can't imagine life without them!
I'm a senior citizen now and was having trouble cleaning the litterbox, when I saw something about KPC and decided to try it. I've had disposable ones before but these are fabulous. I couldn't believe a cardboard box would work, but these are not shipping boxes. The plastic finish on the inside really keeps it dry and in several years it's never, not once, leaked. At the end of the month, I fold it back up, secure it with some tape, cover the "air" holes on the lid (the litter can run out otherwise when tilted, so tape keeps that from happening, and put it back on. A bit more tape, probably not necessary but it made sense and put it in the bin. I had the litter too for a while, but couldn't quite find the right one, but they were all good, just not what I wanted exactly. The boxes are exceptional. Thanks KPC!
