Even indoor cats need constant exercise or else they’ll take their frustration out on your furniture. To give an indoor cat stimulation, provide it with plenty of cat toys along with cat climbing posts and scratching posts. For further stimulation, consider donating to a Kickstarter campaign to create a cat wheel that resembles a giant hamster wheel.
The idea behind this cat wheel is to look good in your house while also providing your cat with a way to burn off excess energy by running. Now instead of your cat running through your house and knocking over valuable and fragile objects, your cat can run on a giant wheel instead.
