Sounds like the same seat I have. I don' t mind a couple nibbles here and there, but when they take to building a nest on the platforms, they' ve gone too far. I had a Loggy climber I would use tree steps to get into. I' d leave it in the tree cause I loved the stand once it was installed, but was loud and cumbersome. I' d tear down a nest today, damn rat would have another built the next. He finally gave up tho.
