If you want your cat to experience the outdoors safely, you can teach it how to walk on a harness and leash. Harnesses are adjustable, so a standard cat harness should fit your cat. Make sure the harness is tight enough - you don't want to lose your precious pet!
Cats don't like to feel restricted, so use a lightweight nylon leash that's about four to five feet long. Most cats won't walk on a leash naturally - you have to teach your cat how to do this.
Make the experience as pleasant as possible. Associate the leash and harness with play. Drag them around on the floor and let your cat chase them.
Put the harness and the leash on your cat while it's inside. The first time you take your cat outside, carry it to a quiet, safe spot in your yard, and gently set it down. Some cats are more afraid than others. If you know your cat is startled by loud noises, pick it up when a car drives by. Always pick your cat up if another animal comes into your yard.
Gradually, your cat will become used to the sights and sounds in your yard. If it refuses to walk on the leash, have someone else stand in front of it and offer it treats. When your cat does decide to walk, let it lead the way.
Be aware that your cat will be exposed to some dangers and parasites outdoors. Your cat can pick up fleas and worms and contract diseases. Also, some experts claim that walking your cat on a leash leads to negative behaviors such as yowling persistently at the door or spraying urine indoors. How your cat will act depends on its personality. Get to know your cat before you to walk it on a leash.
