There are advantages to having two cats, but they are only possible when the two cats are well matched and have enough physical space to coexist. The first benefit is that the two cats can communicate with each other, provide social interaction and other forms of mental stimulation. Cats housed together have more opportunity to “be cats”, to play with each other, which means that they will be less pests or destroyers. For example, some cats annoy their owners because they try to wake them up at night to play.
Two cats could wake the owner by running around the house, but at least the owner doesn’t get out of bed to entertain the cat. Another benefit of having two cats is that they sometimes take care of each other. Cats will groom each other’s ears and often reach places that one cat cannot)
