I saw this on the VEVOR website but decided to order it here since I wasn't familiar with the company. I used to own a One Fast Cat wheel, but gave it away when I moved. I like the VEVOR one much better, it has a narrower footprint since the wheels don't stick out on the side, which means you can slide it up against the wall. I also like how the inside of the wheel is covered in actual carpet instead of the foam squares. This wheel is quieter than the other brand, and the wood pannels are pretty. Some of them even had some nice chatoyancy! Assembly takes 1-2 hours, don't rush because you don't want to make a mistake and have to redo a step. They provide an actual screwdriver, but halfway through I realized I could be using my electric drill. That made things go a lot faster. I suggest having someone help you hold pieces steady as you work, but I was able to do 3/4 of the assembly before asking for help. They also provide a feather wand to help train your cat to use the wheel. My cats seem to prefer this wheel to the other brand, I think maybe because it's a little heavier and feels sturdier, and is quieter. It also looks nice, the product photo doesn't do it justice. You don't need a special breed of cat! As you can see, the cat in the photo is just an average domestic shorthair, and she uses the wheel the most. If you're concerned that your cat won't like it, that is a possibility but most will eventually use it if you work with them. The cat's age doesn't matter, I have cats who readily use it and we didn't get a wheel until the cats were already a few years old. Small kittens will usually use it without any prompting or training, in my experience. If your cat won't use it, look up videos on YouTube on how to get your cat to use a wheel, there are lots of strategies that work, but the most important one is patience. These wheels are fantastic for your cat's health, especially if they are inside all day.
