It depends on your personality and your lifestyle. Cat people have their preferences, but every cat, even within a specific breed, has its own personality. The best way to choose a cat is to go to your local shelter. Look at the adult cats as their personalities are formed and you know what you're getting. Observe the cats and interact with them. Often, shelters even have purebreds available. But keep in mind that it's the cat's personality you're looking for. And you'll be saving a life. If your heart is set on a purebred, Persians and Ragdolls are usually laid back and good choices for first time owners.
