Games with bells
Outdoor cats usually get their daily exercise easily. Cats that spend their days indoors are a different story. Fortunately, you can mimic outdoor activities very easily indoors!
Climbing is essential for a cat and it is good for its nails. So get your cat a scratching post. The advantage of most scratching towers is that they also have lots of spots for your cat to snuggle into.
Hunting can also be imitated perfectly in the house. How about a wad of paper, a feather or bells on a string? Laser lights are also a favourite with many cats. Shine them a bit higher on the wall, so your cat really has to jump up to 'grab' the light.
