Oh they will use them I am sure, I know our local shelter is always looking for mats, blankets, quilts etc. When I was crocheting a lot I use to do alot of little blankets for them with scrap yarn. I would walk in there and see little blankets i'd donaten either in the doggie or kitty kennels all the time. I've not made any since I've been quilting more but maybe this summer. I know I plan to take some of my f1/4's and put them together just to use here at home to put in the chair seat and maybe help with some of the fur everywhere.
