How to Train Your Cat to Remain Indoors

Secure any exits, as cats can be very cunning. A few seconds with an open door is all they need to make a break for it. Keep a spray bottle of water handy, and spray the cat with it if he gets too near an exit.

Make the indoor area as interesting as possible. Provide toys, scratching posts and play areas laced with catnip. If an indoor environment is stimulating, then the cat's urge to explore elsewhere may diminish. Climbing trees and high perches make especially good spots, allowing the cat to feel secure and watch the indoor area from above.

Clear off windowsills and similar areas, so your cat can look outside. An indoor cat may want to watch the birds or sun himself in a pleasant area. Windowsills with spots for perching--especially those high up or on a second story--help him engage with the outdoors, without having to spend time there.

Mix outdoor dirt into the litter box, as it may take time to train an outdoor cat to use the litter box indoors. Start by lining it with dirt from your backyard or another familiar outdoor area. Over time, gradually mix it with cat litter, using greater amounts until the box is entirely full of litter.

Take time to play with your cat. If you want to train him to remain indoors, you must keep the environment stimulating and interesting. Set aside 20 minutes or so each day to bait the cat with string, catnip-laced toys or dangling lines that he can stalk and chase.

Provide a companion. Indoor cats invariably benefit from fellow felines that help make their lives more interesting. A second cat from a local pound or shelter not only provides a stimulating environment, but may also help the cat socialize more readily.
