With all the talk about refillable trays, I'm definately thinking about making my own. There's a company in my area (TAP Plastics) that sells plastic sheets, etc., and will even custom fabricate!
So here's my question. If I do make a reusable tray, how does one empty it after its full of waste? Take it to a trash can and dump? That seems pretty darn messy, especially the poo flap part. Liners seem to defeat the purpose, and my cat is a digger.
