I use the crystal litter also and have the same problem. Right now it's ok, because I'm having to vacuume very day anyway, since we have so many fleas at this time. I do like the crystal litter. It's the best one I've found that I can afford, for exactly what you said. I'm not sure I'm going to continue using it though. I don't like my dog to have to walk in it.
