Mine will poop and pee as many times as he can on all the pads while I'm at work!  Ha ha.  I swear I don't know where it all comes from 

  I guess I am stuck with all 4 pads around the house, as I am too scared to try and remove any.  Also, I place folded up white trash bags under my pads b/c the urine seeps through

  This has seemed to work at protecting my carpet, thank goodness!  Unfortunately, for weeks or months I didn't realize that....Yuck!!!  I have gone through a lot of carpet cleaner.
