A: Hi Marcia! Great question! Yes, we make the Cottontail using Superior Cotton Rope, which shreds apart very easily -- a strand is not strong enough to wrap around a toe, foot or neck. Like any toy with knots, you could get a nail caught in one of the knots, but they generally very tight. Several of our conures have them and love them. I'm adding a picture of our Nanday, Cato, surrounding by his Cottontails!
