I know the rule of thumb is one box per cat. I have 5 cats and 3 boxes. I live in a two room studio and litterbox space is limited. I've noticed the cats use one box more than the other two and the litter has to be changed alot more frequently. I've noticed that when I walk into my apartment, I can smell the litterbox odor after only a week (I use Feline Pine). I remove the solid waste twice daily and when it turns to sawdust, I dump the box and start all over.

SHOULD I get another litterbox?? I can put another box in my bedroom if I have to.

What do you think?
