Yes, the trough hangs by quickly. Also goes not help in the construction. So what, you did not have anything from shoelaces belongs? Just at the outer edge (180 ° to the root) a small hole through the respect and with a long lace depend against the trunk. For timid natures: take 2 laces at 120 ° -Distance. Done it all is wonderful stable. I have already read some that you have backed up the hollows with hook against the wall, but that seems to me then but exaggerated :-). My big cat weighs about 7.5 kg and so the well is stable (with laces).
