I feed my fur children Fancy Feast. For the longest I have saved these inserts, because ya know they have to be good for something, right? So after seeing @joe posting about chipboard, the ah-ha moment hit. Free mew pew sheets!
Fancy Feast FTW! I started saving the inserts about a year before my arrived, and I find that they work very well for a variety of projects.
Oh, yes. I have a stack of them and they are superb for making little boxes with.
When you run out, you will need to get another cat.
