I bought the tunnel on 28 February 2014 and disposed of him beginning in January 2015. In time, the two cats had a lot of fun with the tunnel. The new tunnel rustles much less in any case. The little plaything was demolished after about 3 minutes, but that is not now so tragically. After about half a year, the outside edges were porous. In order for the tunnel openings remain stable, a metal ring is pulled there, whose ends were not rounded. As soon stung repeatedly, the metal spikes from the edge and then I have the tunnel disposed. The ends were so acute that one certainly can cause injury to themselves, the animals so well.
Fun has therefore made in any case the tunnel, you just have something to watch if the lifetime of the tunnel comes to an end. Color-appealing I find the tunnel at most colorblind. A feast for the eyes he was in the apartment before.
For almost 12 I can recommend the tunnel in each case. If the tunnel is not as fast have an injury, I would definitely rate it even better!
