I didn't train my girls to use the pad, but I did buy the Iris to use indoor when I adopted Tia. She came with everything (worms, ringworm, etc.) and I had to separate her from her sister. It is easy to take apart and travel with too. (Be careful with the puppy pads. Tia had to be taken to the ER because she kept eating them and choked.)
Purchase the IRIS 4 Panel Pet Pen at Walmart.com. Save money. Live better.
I purchased a used Superyard XT from Craigslist to train them to potty outside. I put them in that until they went and then took them out. They learned the word fast and I didn't have to chase them around the back yard. Good luck.
