I never have this problem with Patches or Ted E. Bear. Not with any of my other Syrians either. This only happens with my little hybrids, Toffee & Almond. I gave it up and I clean them every morning. I find that if I let it go the cage smells and I don't like that. It doesn't take very long so I don't mind cleaning the wheels. They (Toffee & Almond) are maybe 1/3 the size of my Syrians and at least twice the work LOL.
