Set some time aside. Use the included Allen keys. Build the running wheel. Now your cat has an indoors place to run. Save the local wildlife.
Exercise helps to reduce stress and anxiety. Get your cat a cat hamster wheel. Calm their nerves with some run time. Get all their energy out on the wheel rather than scratching your lounge.
Cats are natural hunters. They might not have any prey inside, but they can run on their cat exercise wheel. Give your cat an outlet for their instincts. Watch them run at full speed.
