Anthropomorphism

From Webcomic Wiki

Anthropomorphism is the attribution of human characteristics and qualities to non-human beings, objects or natural phenomena such as animals, or forces of nature.

Anthropomorphism is a well established device in literature, notably in books for children, such as those by Beatrix Potter and Lewis Carroll, involving characters such as Peter Rabbit and the Cheshire Cat, respectively.

Anthromorphism is a characteristic of many webcomics, commonly referred to as anthromorphic or furry webcomics.
