Awww - poor sweetie. While you're at the Drs. Foster&Smith website, look around at the other types of perches they have. When I got Skye, all he had were wooden dowel perches, so I ended up replacing several of them with some all natural ones, a rope one (that one is still hanging from the side of his cage so he can get used to it, lol)and a great mineral block perch. It's a good diameter for him, he can munch on it, it's a tasty orange flavor (lol) and if the roughness might be a problem, I imagine a some quick swipes with some sandpaper would fix it. (Of course, rinsing well afterwards.) I've also heard of cork perches someplace - it might have been at the same website. If I can find it again, that'll be the next one I get for Skye.
Good luck!
