These rattle tubes are made from 3/4" PVC pipe 6" long that I put BB's and bells inside. I cover the ends with a piece of cotton fabric. Then I cover the tube with a piece of short to long pile faux fur using a water soluble, non-toxic glue and hand sew the ends shut. Your cat will have a great time scratching on these toys. Surface washing is recommended.
Note: The glue used is water soluble, so don't drop them in the water bowl, wash them in the sink or washing machine or do anything else involving water with these toys because the fur will come off the outside.
