Why cats tail always stand up?

A cat's tail does not always stand up. In fact, a cat's tail can be in a variety of positions, each of which communicates a different message. For example, a cat's tail may be:

- Up and arched: This is a sign that the cat is feeling confident and happy.

- Held straight up: This can indicate that the cat is feeling alert and curious.

- Flicking back and forth: This can be a sign that the cat is feeling playful or excited.

- Tucked under the body: This can be a sign that the cat is feeling scared or defensive.

So, while a cat's tail may sometimes stand up, it's important to remember that this is just one of many positions that a cat's tail can take on. Each position has its own meaning, and it's important to pay attention to the overall body language of the cat in order to understand what it's trying to communicate.
