Hi.
I have 2 Great kittys Shorty and Idgy I have learned that I can cut down significantly on any litter getting tracked around the house, and "sweep ups" by putting door mats in front of the cat box entrance. Of course this only really works with an enclosed cat box. But it works well and I can take the door mat out and shake it out. No litter trails no sweep ups and no litter in the vacuum cleaner. I like it. It works!
Vivianz... Shorty and Idgy's mom. :)

True, true...I do the same plus I add another outside the cattery door...

I have a doormat at the bathroom door and two small carpet squares just by the litterbox. Gizmo always wipes her feet on the box, not on the carpet, but the three bits of stuff keep the litter in the bathroom. I've never seen it tracked outside.
