Timber's main area of "clumsiness" is getting his nails caught in things. That is something they don't deal with as much in the wild. Rugs, grills etc. are natural "nail catchers." When they are in the cage, their wings (that they use for balance in the wild) hit the cage sides, bars etc. What I'm trying to say is that the things we have in our house aren't their natural habitat, hence the "clumsiness." Hope that made sense, but it's already been said by others on this thread anyway!
