Do animals feel pain

Animals typically have a central nervous system, much like humans.

The pain that they experience is unique to each animal, however some animals can feel pain in a way that is more extreme than the human experience, and others might experience the same amount of trauma in a different, more subtle way.

-If an elephant is hit on it's rear with a human hand, it will feel pain in a lesser way as compared to if a child is hit on it's rear, or a kitten is hit on it's rear.

However, some animals lack a central nervous system, such as oysters and sponges. If there is no central nervous system, there is most likely no capacity for pain. Animals with no nervous system whatsoever can't even feel anything.
It depends on what you mean by the term "hurt".

For example, if you hit an animal, like a dog or cat with an object they react to the action cause it may hurt of does hurt. in addition the animal you are hitting may become angry or may fear you (which shows a sign of emotion).
