Indoor cats need regular exercise to maintain a healthy weight and prevent boredom. Here are some fun ways to keep your indoor cat active and mentally stimulated:

1. Interactive Toys: Use wand toys, laser pointers, or remote-controlled mice to encourage your cat to run and jump.
2. Climbing Structures: Cat trees or wall-mounted shelves provide vertical space for climbing and perching.
3. Puzzle Feeders: These make your cat work for their food, providing mental stimulation and slowing down fast eaters.
4. Scratching Posts: These allow cats to stretch and maintain their claws while providing exercise.
5. Hide and Seek: Hide treats or toys around the house for your cat to find.
6. Cardboard Boxes: Simple but effective, boxes provide a place to hide, jump in and out of, and explore.
7. Training Sessions: Yes, cats can be trained! Short sessions teaching tricks can provide mental stimulation.

Remember to rotate toys regularly to keep things interesting. Aim for at least two 15-minute play sessions per day. With a little creativity, you can ensure your indoor cat stays healthy, happy, and active.
