Thanks everybody for your posts!
What would I do without YT??? I tried for a day and I half to take Sophie outside to go potty...and she was doing it! No more pee pad shredding. However, I don't think going outside will work now, becasue when I am not home, she goes on the floor in her xpen. I could crate her i guess. The other thing is...When I take her outside, I have to leave my 2 year old unattended. We are in CO and it is freezing cold outside. I cannot take my kids all out w/me. Also, I will never be able to let Sophie out to go potty on her own, becasue we have coyotes and hawks in the area. So...long term, I am now thinking outside is not such a great idea either. Maybe she will grow out of shredding the pads? Has anyone had a shredder that stopped when it got older?
