I just put the pee pads inside the litter box. When I first got Jasmine, I tried it with the litter, and she just made a mess with it. Just the pads seem to work well for me. I usually change them about twice a day, and Jasmine is 8 mo. old now, and no accidents. Yeaaaa - :lol:
I tried to use newspaper after starting off with just pee pads because I thought I have plenty of newspapers around and what money I could save! But, newspaper is not absorbent and it just seemed too messy. I line the floor with newspaper below the box, since Jasmine sometimes sticks her butt over the edge to poo (wierd!) but now I line the box with newspaper and put the pads on top. That way, if I have a cheaper pad or the good ones leak, the box stays cleaner and I sometimes can leave the newspaper for quite a while. It is just a little extra protection, I guess.
