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".
Yes, animals have emotions and can get hurt physically and emotionally.
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).

Obviously, at least the ones with the capability to feel pain. That is, unless you get a clean headshot which destroys the brain.
Oysters do not have a central nervous system, so they do not feel pain in the same way that humans or other animals do.
Yes, animals may experience pain during and after being neutered. However, veterinarians typically use anesthesia and pain management techniques to minimize discomfort and ensure the animal's well-being.
No. Pain is merely a signal sent to the brain and the brain registers the pain. Bacteria lacks a brain, therefore can feel no pain.
most experiments on animals are harmless even if they look bad. animals feel less pain then us and are very oblivious. insects can not feel pain at all. and there brain is too small to know whats happening
The scientific consensus is that clams do not feel pain in the same way that humans or other animals do. Their nervous systems are not as complex, so they likely do not experience pain in the same way.
Yes, animals that lay eggs do not feel pain during the process of laying eggs.
I have no doubt they do. All animals have nerves and the main function of nerves is to sense or feel things in their environment.
Yes, pigeons are capable of feeling pain. They have a nervous system that allows them to experience sensations, including pain, similar to other animals.
The scientific consensus is that oysters do not feel pain in the same way that humans or other animals do. Oysters lack a centralized nervous system and brain, so they do not have the capacity to experience pain.
All animals (and perhaps all living things in general) need to respond to negative stimuli in some way or another. However, not all animals will feel "pain" like we do. Human/mammal pain goes deeper and the suffering can be much more intense. However, some animals lack consciousness and can't feel pain like animals with brains. Examples include jellyfish, clams, corals, anemone, sponges. Pain is an evolutionary feature intended to cue animals to escape to ensure survival. Several animals such as sponges need not escape, as it can reproduce simply by budding and even being shredded alive.
