Good question!
According to Google, and some given thought:
"It/It's is a neopronoun and is used by many individuals already. While traditionally it is used to refer to non-human subjects, it has been used for sentient and self aware and anthropomorphic individuals throughout mythology and culture. Pronouns are to make YOU feel comfortable."
I think it can be both, but Google provides a good argument (not that this is an argument!)
Hurray for both neo and standard pronouns! :3
