1. Look into the kitty's kennel and BLINK with both eyes slowly a few times. See if he will blink back at you. This shows the kitty you are not a threat, since cats stare intently at other cats when they are aggressive or afraid.
2. Toss or drop a toy near the kitty. If there are no toys in the kennel with the kitty, make a loose ball of a piece of paper or a post-it note and place or toss it near the cat or kitten. This lets them know that you are interested in giving them gifts and playing with them.
3. Offer your hand to be sniffed. You can make sniffing noises also, to add to the cat's greeting. This shows the cat you are willing to be investigated, as another cat would in the same situation.
4. Stroke the top of the cat's head, and along her back, stopping at mid-back. Some cats are sensitive about having their flanks petted. This pleasant exchange lets the cat know in another way that you are a friendly visitor.
By this point you should have discovered whether the cat is accepting of you. If all goes well, you can brush or comb the cat, give him treats, and even pick him or her up. Investing a few minutes in relationship-building with a cat will help you choose the right companion and begin a relationship that will last for years!
