I say you just stick to the method that works best for Tippy. In this case it seems like the potty pads worked best. I only had my Snickers for 2 weeks and he is already doing great with the potty pads. I am going to try the outside training after he gets his last shots. Keep putting her in the litter box and she will get the jist that she has to go potty in there. Hope this works....Always remember praise her and give her a treat when you put her in there....BEST OF LUCK....
