I fill pillowcase/pillow size with all my tiny scraps/batting leftovers etc and serge them closed. They are all shapes and sizes. The shelter I donate to gives out a bed to new owners when the pets go home. The only thing they request is that it is has not been used before by another pet. All my quilting/sewing buddies save me their scraps. I have a bunch of big bags of stuffing I need to use!
