Single Kitten (or Cat) Syndrome is a collection of behaviors including, but not limited to, biting, scratching, going outside the litterbox, loneliness, boredom, aggression, excessive vocalization, picky eating and disrupting the household during the night.

Although we generally think of cats as independent, aloof or loners, they are actually quite social- and group-minded, and learn acceptable behaviors from other cats, mainly a mother cat or mates of similar age. Cats adopted before 12 weeks old and raised in a single cat household will not have had the time to develop and learn behaviors that are acceptable.

Without feedback from a mother or sibling, kittens do not learn which behaviors are too aggressive, such as biting or scratching, or what to do with themselves when bored. This can lead to destructive behavior in the household or aggression when not warranted, such as biting or grabbing ankles as a person walks by.

Kittens are a barrel of energy and need a lot of attention. If you work away from home and the kitten is left alone for many hours per day, it will find something to amuse itself — usually an unacceptable behavior. If the kitten has a mate, a lot of its energy will be spent playing, wrestling and chasing the mate, leaving the quiet, snuggle times for you.

Kittens and cats need environmental enrichment, which can be provided through television, a cat tree near a window, interactive toys or puzzle bowls, and, of course, a playmate.

Now you maybe thinking that this is just a made-up idea to get more kittens adopted out of the shelters. However, if you speak with a rescue or shelter worker, they will confirm that two kittens generally do better than a single. The majority of owner turn-in cats have been raised as singles and are displaying unacceptable behavior as adults.

It does not cost double to raise two kittens, as most items (beds, toys, dishes, litterboxes) are shared. To have two happy, well-adjusted kittens is a far better option, and will bring much joy into your life. If you are looking to adopt, please consider getting two kittens (or cats) and take advantage of the discount offered by most rescues.
