Relaxed
Focused
When a cat is on the prowl, its whole body attunes to the object of focus. You can see this body when a cat is hunting. Whether its prey is a toy, insect or mouse, the cat's body is low to the ground as it stalks. The cat coils its hind legs beneath it as it readies to pounce. (Source)

Playful
Cats show playfulness by wriggling on their sides or back. They could be meowing while trying to encourage you to play. Their position could start on their sides, but they may move to their back as they roll around. Cats are trying to convince you that they are harmless and are looking for fun interaction. (Source)

Confident and Content
A cat lying on its back with its belly exposed indicates a feeling of confidence and security in its location. But it is also defensive. The cat may be in a prone position, but it has all four legs up and is ready to attack if need be. People who try to rub a cat's tummy when it's in this position will learn that lesson when their hands get bitten. (Source)

Neutral
This is how cats spend most of their days. They are comfortable and content. Cats could be lying down or curled into a ball. There is no tension in the body. They are happy to sit and watch the world go by from this position. (Source)

Fearful
The arched back indicates fear. Cats do this to make themselves appear larger, and their fur stands on end. They are viewing something in their environment as a threat, and use this position as a form of defense. They are ready to strike at whatever is driving their fear. (Source)

Anxious
Cats' heads drop lower when they are feeling anxious. Their ears flatten back against their head. Cats may cower as they try to make themselves smaller, often crouched into a small, tight ball. They could be feeling like they are literally or figuratively backed into a corner. (Source)
