Group housing for cats has benefits in many cases, but housing more cats per square foot is not one of them. In fact, cats in group housing need more square feet of floor space than those housed singly. This is because group-housed cats must use distance to manage their interactions with other cats since they are not protected by a physical barrier.

To determine how many cats should be housed in your group cat rooms, all you need is a tape measure and this handy dandy group housing calculator.
