Type of flooring can make a big difference. Tile/hardwood is easier to clean than carpeting, but the litter tends to scatter in a half mile radius. Carpet keeps it right there. If you have a small dustbuster type hand vacuum you can keep nearby, it can be a solid way to deal with them. Depending on how aggressively she digs and flings the litter, you might be able to make a difference by taking the lid from a larger storage bin and flipping it upside down, then place the litter box on that. The small lip around the edges can do a great job of containing things for some cats --- and absolutely nothing for others. Bit of trial and error, that.
Thanks for this. This may prove to be excellent advice. In fact we have two hand-held vacuums, a Dirt Devil and a Shark. So it may just be a case of figuring out a good spot to move the box from the powder room. The one in the downstairs bathroom can stay there, I think (we ourselves use that one less frequently), but it would be nice to free up the powder room.
Lots of things to consider.
Also, "a solid way to deal with them" is an outstanding (if perhaps unintentional) pun, given the context.
