Salad Roller Ball theratshop.com - $8.00 Product Description: It's nutrition and fun rolled into one! Our Rollin' The Hay Spinning Hay & Salad Dispenser can be used three ways--on the stand, hanging inside any wire cage, or free-wheeling anywhere. RattyRat's Review: Our rats didn't have much interest in this toy when it was filled with hay, however when we filled it stuffed full of plain white paper towels, our rats had a blast with it. This toy is a very inventive and fun way to provide your rats with the materials to make a nest out of. Be sure to have many of the paper towels pulled out between the bars so the rats can get at them, plus if the paper towels are poking out all over, it will be more inticing to the rats. Better yet, after you stuff it full of paper towels, put a bunch of plain popcorn in it. It will be a nice surprise for your rats to find. This toy is great and attaches right to the side of the cage, and the ball comes off for easy use to refill.
