* Squeals can be happy sounds: Piglets often squeal when they're happy and playing with each other.
* Squeals can be warning sounds: If a pig feels threatened, it might squeal as a warning to others.
* Squeals can be a call for attention: A pig might squeal to let its humans know it wants food, water, or attention.
So, there isn't one single thing a pig wants when it squeals. It's more about expressing different feelings and needs!
