My hedgehog likes this but I have to watch her like a hawk when she uses it as I am afraid she will get a nail caught in carpet. This hasn't happened yet but she does use her wheel more. The ball itself is sturdy and well made. Was easy to put together and came with spare studs. Easy clean.
I bought this for my pygmy hedgehog.. It is not totally silent but is quieter than I expected. The plastic construction is sturdy and well made, my hedgehog uses it daily and loves it. Easy to clean. I use it freestanding and have had no problems with it toppling over. Highly recommend.
