Lol - I can feel your pain.  My furkids would shred the disposable pads, especially the ones that contained baking soda.  I solved my problem by switching to the washable type.  I purchase mine from 
http://www.valethics.com  They are reclaimed from hospital/nursing home use and are thoroughly cleaned before they are shipped.  I have been 100% pleased with these pads.  They are very inexpensive and wash well - they have a nice heavy cloth covered rubber backing that DOES NOT LEAK.
