I have pads for Cookie, also, I use a large plastic toy box that I got from a hardware store. I fill it with cat litter and after she wakes up, pees on the pad, I put her into the what I call the poo-poo box and tell her to 'wee' (yeah, I know it sounds silly, but I can't bring myself to say poo-poo) and I tell her to 'stay' and I sit or stand close by and I don't let her out until she does one or she sits down and cries (which is her way of telling me that she doesn't want to do a poo) - if she does get let out of the litter box, I watch her or I call her to come to me and that way I can keep an eye on her so if she stoops, I pick her up immediately and place her into the box.
I find this to be about 98% effective (I sometimes don't catch her in time and when I am taking her to the box, she can't hold on anymore) also, Cookie likes to have privacy so that is why I have the toy box as it has tall sides - she will on the odd occasion poo behind things or under them.
I hope this helps
