In fact, over 56 percent of the cat owning households in this country have at least two cats living under one roof, according to a survey by the American Pet Products Manufacturers Association. So, if you feel that more is merrier, make sure your house is equipped to handle the needs of multiple felines. Here are some things to keep in mind: To minimize cat fighting, make sure you have at least one litter box for each cat. And, some experts suggest having at least one extra box somewhere in the house, or making sure there is a box on each floor of the house. Provide many places for cats to hide out and perch. Scratching posts, beds, food and water should also be available in several locations. If you decide to become a multi-cat household, take great care in the way you introduce a new cat. Many experts suggest putting a new cat in a room of his own for a couple of days. Then put your new cat in another room and let the old cat come into the room and sniff out the new cat's scent. Start actual visitation slowly and see how it goes before letting both cats have free roam of the house. Before you get a second (or third) cat, remember this: the major reason cats are brought to animal shelters is that they could not get along with the other cat(s) in the house. --Jura Koncius, Home section I'm really more of a dog person, but found these tips from WashingtonPost.com interesting.  Enjoy!
