I made some pet beds stuffed with scraps. I sewed large channels end to end in my pillowcases to prevent the 'smooshed to sides-flat in the middle' syndrome. It's a little more difficult to stuff, but works well. I can see how they would take a long time to dry. I donated them to the local animal shelter.

our little sewing crew combines all the crumbs and batting pieces and puts them in pillowcases. Batting might need to be chopped up some so it doesn't bunch. Sew the end shut and make a case with flannel or fleece so it washes. Our animal shelter likes them- don't overstuff...our local vet also uses them for after surgeries, she likes them as well, and washes them, they last for a bit- always willing to take more!

I don't use fleece at all. Just good old sheet material scraps. fabric that hair washes out easily. I keep the fabric for the doggie beds separate from the other fabric. When I wash it after getting home, I use unscented dryer sheets. This helps any static cling that attracts animal hair.
