Article: Looking outside can be very stimulating to your cat, so make sure there is a window in your cat room and that your cat is able to sit in the window sill.  If the sill is not large enough for your cat, place a piece of furniture or a shelf directly beneath the window for your cat to sit on. You can also purchase cat perches that are specifically designed to be attached to windows.  Cats also love windows because they let in the sunshine. Cater to your cat's love of the sun by providing soft places to sleep in areas where the sun shines at different times of the day. Large windows, particularly full-length windows and glass doors, might make your cat feel uncomfortable in her space if there are cats or other animals outside. You can make her feel safer by applying an opaque film to the bottom of the window and providing her with a perch from which she can look out the top part of the window, or by placing other items, such as plants or pieces of furniture, in front of the window for your cat to hide behind if necessary. If possible, let your indoor cat enjoy the outdoors safely by giving her access to an enclosed outdoor pen or "catio". Position the pen directly outside the cat room and install a cat door to allow your cat to come and go as she pleases.  You can purchase or build an outdoor cat pen, but make absolutely sure that it is secure enough so that your cat cannot get out and no other animals can get in.  If you can't give your cat an outdoor enclosure, you can still provide her with some plants to help make her feel like she is outside. Cats like to munch on plants, so be absolutely sure that you choose varieties that are safe for cats.  Cat grass is probably the best option, and it's easy to grow yourself. Indoor cats can get bored if they are not provided with stimulating activities. To keep your cat active and entertained, make sure she has a variety of things to do.  Make climbing a challenging activity by providing a variety of perches and shelves around the room at different heights. If possible, create a climbing course that allows your cat to navigate the entire perimeter of the room without touching the floor. Scatter lots of small cat toys, like toy mice, around the room, or place them in a basket that is easy to access for your cat. Puzzle toys are a great way to keep your cat busy. You can hide treats or toys in them and your cat will need to figure out how to get them out.  You can also purchase high-tech toys that are motion-activated or move randomly to keep your cat's stalking instincts sharp.  To keep things interesting, move things around and add new challenges on a regular basis.  Keep in mind that cats don't need expensive toys to be entertained. A winding tunnel made out of a series of cardboard boxes could provide hours of fun! Be creative.
