Our two kittens absolutely love the cat tree. However, within 5 minutes one of them had pulled one of the mice off the tree and the other two weren't far behind. We have to keep inserting the sticks with the mice on back in the tree as the cats like to pull them out. Unfortunately the grey soft fabric has also started to come away in some places.
This all is manageable though and for the price you would expect this level of quality.
