Choose a quiet time to massage your cat. Your cat may have just come in from outdoors or he may be in the middle of cleaning himself. Wait until he’s not busy with something else before initiating a massage. Wait about 2 hours after your pet has eaten before massaging him. This will give him a chance to digest his food. Get close to your cat and make sure that he's happy to be in your presence. You may even want to wait for him to come to you instead of grabbing him out of his comfort zone. Wait for him to hang out with you, relax, lie down, or even to purr or nuzzle up against you. Make your kitty feel calm and happy by getting him into the right state of mind first. Start by singing lightly to your cat or using a low, calming voice and telling your kitty that he's a good boy. Don't use the high-pitched, squealing voice some people like to use to talk to cats ("You're such a cute little kitty!!") or you'll actually stress out your kitty even more.
