Some people think animals don't feel emotions perhaps out of a lack of empathy or a backlash against anthropomorphism either way I have a hard time agreeing because dogs seem ******* when they growl and there has to be a mechanism to trigger that.
Factors like language and cognition differentiate humans and animals so I don't think a dog wonders why it's relaxing on the floor while a buck's head hangs from the wall. But I do.
I wonder what goes through the mind of a doe as it watches its fawn get hit by a car it may not feel the same depression as us but it had an instinctual obligation that has been abruptly removed there must be some friction in its mind between what is and should be.
I've felt that friction for animals before like when I was at my friend's house he saw a big spider (by Kentucky standards) and crushed it dozens of tiny spiders crawled from its corpse shocked and disgusted my friend started stomping on all of them as I watched I felt bad for the spider she was a mother that failed her natural duty due to forces much larger than her all it took was the wrong place and wrong time for the result to be crushing failure.
I wonder if animals are more like humans or if humans are more like animals because there are plenty of people that make me wonder if they feel any emotions.
