Snuffy shredded her pee pee pads too. I'm not sure why they do it either because she has plenty of chew toys. My mom brought home these pads similar to pee pee pads from her work and I put them underneath the legs of a chair so she can't really move them...she hasn't shredded one since. I also heard there were some kind of holders for them to keep them in place?? As far as keeping him crated when you can't watch him..I'm not sure. I would whenever you leave the house. Good luck!!
