meant nice, but dangerous!

This perch that (ie a branch of a tree) is made of natural wood and a tied ropes are a good idea. My four parakeets loved it, the evening public office rumzutollen it and the "four-team" nibbling to work the ropes. I thought it would be a great challenge for employment and my budgies. Until one day a budgie had caught in a snare. His head had somehow fallen into the snare and no longer got away. In my attempt to free him by cutting with scissors, he flew in his panic around aimlessly, but came not from the spot - on the contrary, the noose tightened to more firmly. Somehow I managed it but to cut the rope through. The poor guy was sitting for some time disturbed in the corner, but recovered quickly. I immediately removed the perch.
The images, however, I will never forget well!
In a budgie forum I had already read that this article is very dangerous, but did not want to believe it because my budgies were so happy with it. Today I can only warn every animal lovers - it does not do to your pets !!!
