If you are used to cleaning up litter, then it is not an issue using whatever you have on hand. However, that voice in the back of your mind reminding you that you are using something that is not composting or eco-friendly just drives you crazy! Or, at least, that was my voice:)
I am glad I found these, and you get your money's worth! You get a lot of bags and can fit a good bit of litter in them! they sort of have a little bit of stretch to them, allowing you to fit whatever business inside until you see fit to tie it up and throw it out.
All animal owners need these!

We used to use plastic bags for cat waste but now we are starting to use these. They hold up great and block scent really well.
