Hopefully someone here may have experienced this before.

On a brighter note the cats have been very happy to use the boxes I topped off. I hadn't realized that gradually they hadn't been using those boxes as much. I've already had to clean them 3 times today, they aren't really using any of the other boxes now.

I guess tomorrow when I go to the pet store, I'll not only get more of that litter, but also the shaker can of the herbs to freshen the box between changings.
