You CAN train them to go on puppy pads. I use newspaper (puppy pads when I run out) for one of my cats. For some reason, since shortly after I got her, she has never used the box. Now, I think she can't climb into one (problems with her hip.) I used the same technique to train her to use the papers as I do for litter training: Shut her in a room with her box (and the pads), her food, water, bed, and toys and leave her in there until she was going in the right place.
She now uses the papers 99.99999999% of the time. I have had very little problem with her going anywhere else since I've paper trained her. (I prefer newspaper for environmental reasons, and because urine sometimes gets under the plastic backing of the pads and makes just as big a mess as if she's peed on the floor. The paper just absorbs it. ;) )
Andrea had great suggestions, too. I would try different litters and try retraining her. We have another cat that we have to retrain from time to time, and it does work.
Such a frustrating issue! Good luck!
