Stupid childish rant aside, "I'm not meant to inhabit this tomb that "science" calls a body" might be the greatest emo line I have ever read.

This is why I cannot take otherkin seriously. They don't act like actual animals would, their knowledge of animal behavior comes from an entirely Human perspective.

For example, squirrels aren't exclusively herbivores and have diets similar to other rodents. They will actually eat bird eggs if they are available. In general you cannot apply veganism to an animal lifestyle. Animals do not have any moral quandaries about eating other animals. To them meat is just nutrients and even animals thought to be exclusively herbivores will readily consume meat if they are presented with it.
