I have a lot of outdoor material that I got with some other fabric I got off of craigslist and was thinking about making dog beds for our furbabies. I was trying to think of an inexpensive filler (3 large dogs) and for whatever reason, i just thought of kitty litter. It is absorbent and deodorizes and probably 3-4 large bags would fill one bed. Plus every so often, I could empty and replace it. Of course i would contain it in a larger bag inside of the cover.

Has anyone thought of this or done this? Is it a totally dumb idea?
Opinions please?

Thanks!!
