I have two parrots, sun conure and a goffin cockatoo. This is a favorite chew toy for both my girls. The first time I bought this toy, size medium, it lasted 6 months of chewing until it started to look rough. It is still intact and able to take the aggressive chewing. Recently I bought a large size of the same toy. I figured it is one of their favorite toys so a variety of them at different sizes should keep them happy.
