I started teaching her from the first day I brought her home. There is a DVD "Scoop No More" that I used. It took about 2 momths to train her. Well worth the time and effort!
looks like your Izzy is looking at my Molly. Your kitty is pretty & so smart. Our Doodles is Bombay & uses the toliet also. He came to us after he was already trained. Did you teach her or she learned by watching people use the toliet. Great kitty!
