My Jelly is an absolute scaredy cat, but also very food motivated, it took a few tries and rubbing catnip into the carpet but she can now speed walk on the wheel for treats! She's gotten on it herself twice but only does a slow, cautious walk to see if I've hidden any treats in the lip of the carpet, but this is only day four of having the wheel, so it's big progress! It might seem counter productive to give treats while getting her to exercise but I'm hoping that she'll eventually run on it without me prompting her with them. It's sturdy, big enough to fit my cat and slim enough to be put to the side out of the way, it's noisy but so what? It's much more entertaining watching your cat on this than anything else you could be doing! I would recommend a drill when putting it together, but the instructions were easy to follow. We've used it every day since we got it and haven't had any wobblies so far!
