When picking out a cat, make sure you look at the whole package. While it is important to choose a cat that you find appealing, make sure you don't overlook it's other qualities. If you notice a cat crouching in the back corner of the cage, it is likely to do the same thing when you get it home. It will probably hide away under and behind things in your home. If you notice a cat that is rubbing up against the cage and trying to extend a paw out to you, this could be a sign that the cat is playful and friendly. If you make a choice on a cat you like, see if you can spend some time with it out of it's cage. Many shelters will have rooms to get to know your new pet. This will give you a better idea of how the cat will be at home.
