The human version of Enneagram personality type 4 is popularly called the individualist, the romantic, or the original person. Typical characteristics focus on their inner emotional world, finding a unique sense of who they are, and how they are different from others.
The cat version of Enneagram type 4 we call the Sensitive Individualist or the Moody Kitty. The Moody Kitty's attention is on responding to internal feelings.
Your cat is unique and not simply another cat. Acceptance of that uniqueness means not expecting them to be like every other cat.
When your cat is experiencing a mood it may take time alone to process the mix of emotions ocurring within to allow the mood to dissipate.
There will be times when your cat doesn't want to do the things that you want. To force that can amplify negative emotional responses.
To Not Be Neglected
Being neglected might feel like being abandoned or unwanted. Little things can be taken personally resulting in feeling rejected or forgotten.
There may be triggers that create different moods for your cat. Understanding those triggers and what they do can help you respond to what your cat needs.
While the Moody Kitty is uniquely special when compared to other cats, there can be sudden shifts in mood and behavior for sometimes unapparent reasons.
