A cat is usually relatively inexpensive to house and maintain. Their biggest need that cannot be provided through shared use of your furniture is a litter box. Your cat will happily sleep on your bed, climb your bookshelves, and eat out of whatever bowl is provided – or not provided as the case might be. However, cats are territorial and they understand the concept of territory. Given their own spaces, they will happily lounge in them, eat from their personal bowl, and enjoy scratching posts and specialized kitty retreats. Giving your cat dedicated equipment can sometimes save your furnishings from depredation.
