We believe strongly in the value of having another animal in the household with a Maine Coon. That is why we at CaliMaine encourage our Maine Coon owners to have another cat or a dog in the household.
One of the qualities that humans appreciate in Maine Coons is their social nature. By providing your Maine Coon with the companionship of another animal (especially when you can't be at home), you provide an outlet for your Maine Coon to communicate and interact with another animal in ways that are different from the ways your Maine Coon will communicate and interact with you.
Maine Coons can have a strong play drive, and even almost constant human companionship isn't all that a Maine Coon craves. As a benefit, you will enjoy the pleasure of observing the antics of your well adjusted furry family members.

A real life story
Henry (the one-year-old silver tabby on the left) was generally a very cooperative fellow. allowed his owners to comb him regularly and brush his teeth every night. Hurting his humans was not Henry's intention, but as Henry got older, biting became Henry's way of communicating to his owners that he was bored.
Here is what one family had to say after having adopted Dickens (the seven-month-old brown tabby on the right, also from CaliMaine) to give Henry some feline companionship. Reluctant at first to believe that getting a second cat would cure Henry's acquired habit of biting his owners, the family was convinced after just a few days that Dickens' companionship had done the trick. Here's what they wrote to us:
"Dickens continues to add charm and silliness to the family mix. He and Henry are very good buddies, frolicking through the house day and night. Dickens loves Jack [his human dad], wanting to sit on his lap all the time, which is wonderful, since Henry has bonded to me. He is inclined to bring one or two of his favorite toys onto the bed at night just in case he gets bored. We generally stash them in a drawer during sleeping hours and pull them out in the morning, much to Dickens's pleasure. He is a character!
Henry does nothing but get more loving and cuddly as he matures. He is full of purrs and follows me from room to room. He sleeps next to my pillow (sometimes on it) and could not be a sweeter or more lovable cat. I cannot thank you enough for encouraging us to get Dickens for Henry to play with, as it made all the difference in the world."
