Kali started to tear up the paper pee pads too so I was worried about her eating the plastic. I purchased a bunch of cloth pee pads and the problem was solved. She had no problem either adjusting to these from the paper type. Actually, I think it is more economical too in the long run as these pee pads are reportedly good for over 500 washings. They are decorative too and don't look so bad by the back door. Hope the problem resolves for you....
