When I had a house full of fosters, I would buy really large clear plastic bags FULL (20 to 30 small stuffed toys to a bag) of stuffed toys for $2.00, at the thrift store on main street Ventura. I took off any eyes and such that could be chewed off. You should have seen the "toy" room then. It was too funny with about a hundred stuffed toys on the floor. The dogs were in doggie heaven.
