Jen, that's what I use. Donna, Feline Fresh tracks really badly but I'm willing to put up with that. It really does a great job at controlling odors and unlike the clay clumping litters, it doesn't all stick to the bottom of the litterbox like cement. Only once a month do I completely change the litter...then again, I only have one very tidy kitty.

Definitely I would add another box wherever it's convenient. I have two litterboxes for Max, both in the spare bedroom and he does use both. Sometimes he leaves pee biscuits in one and tootsie rolls in the other.....it depends on his mood that day.

Good luck.
