Hi, don't fret girl. I've been through that too, so I purchased one of these ...
Amazon.com: Iris 301551 Floor Protection Tray -... End of pad tearing. I also switched over to washable pads there are some sellers here. It's great, you just buy a few and then that is it, wash them, vs. that weekly worry of having to buy pads. they are quite easy to make too.
Good Luck!
