Superior cotton rope is all natural, and a 100% digestible, and bird safe. Wonderful product!!!! You can divide the 1/2" into three 1/4" strands easily! If you use any other type of cotton rope on your bird toys, please be sure to keep the strands short. If you aren't sure if the cotton rope you have is safe, drop me an email and I will explain how you can tell what type you have. Most cotton rope is unsafe to use with parrots.
