Bests & Worsts Reviews from Amazon

We liked it at first glance. Easy to put together and esthetically beautiful. But within ten minutes of assembling the wheel, our cat tried running on it and got his paw caught in the large gap between the wheel and base. SO lucky his leg didn't break! I appreciate anyone who is trying to build toys for cats, but do not recommend buying this until it is re-designed. The gap needs to be smaller.
