Great idea Laura! We make some of Salty's toys. We have the large plastic balls which we stuff with paper towels. We also use any part of old toys that have not been destroyed and re-purpose them. Right now he is on a kick with anything that is made from wicker reeds, going thru them in 2 days, which as you know, can add up to one very expensive habit! I picked up a bag of wicker cups, so we just restring the wood parts from the last toy, and he is happy.
