Well I’m sorry but only a very incompetent person wouldn’t realize this themselves. It’s not about moose knowledge, there’s no need to be sarcastic. It’s simply about biology. Moose are mammals like us so it is only logical that they have similar neurological structures to us. We can feel itching. I itch when I don’t shave for a few days. They also feel itching so they try to scratch that itch. Something pops off instead in the process. I mean unless you’re one of those unbearable religious people that doesn’t believe other animals have feelings (nervous systems) mammals can feel pain. If you didn’t know that they can feel itching then I assumed you didn’t even know that they know that they are alive.
