Authors note: I realise there is already an existing FAQ. However I find it has succumb to bias and a crude lack of information, or some information being excluded because "the answer should be obvious". So instead, here's a guide that targets a general audience, not just the Otherkin community. Each question has an analytical answer.

This FAQ is answered under the notion that there are variables unable to be scientifically proven due to a lack of human visibility of others' personal experiences and visibility. Because these claims are unable to be proven, they are taken as a possibility rather than an absolute theory.

What is the definition of Otherkin?
An Otherkin is an individual who does not identify as human, usually feeling they are meant to be a different species altogether. They acknowledge the fact their body is still human, but either their soul or psyche do not match their body.

Is Otherkin a mental disorder/illness?

A disorder is defined as a disruption in one's day, whether that be socially, physically, or mentally. For some individuals, being an Otherkin can cause disruption. But for others it may not. Currently Otherkin is not recognised as a disorder by medical professionals. However, if you are experiencing detrimental issues associated with being Otherkin, by all means contact a professional. Otherkin is not something that can be removed, as it's a part of one's identity. For the individual, the healthiest option is the support of one's identity, as long as it is not harming oneself or others.

What are the warning signs?
- Clinical Lycanthropy, when an individual believes they are or have physically taken the form of an animal. Physical shifting is impossible. Humans do not have the organic ability to transform their body into something non human, or at least this has yet to ever been witnessed.
- Having a great deal of trouble or stress when interacting with human beings, see a professional for further advice.
- Believing you can see things that others cannot. A human body comes with human eyes, if you believe you are sensing or seeing entities that others claim are not there, seek professional advice.
- Harming yourself or others due to variables associated with being Otherkin.

What causes one to feel they are Otherkin?
There is no single common denominator of reasoning for Otherkin. As it is a part of one's identity, it can heavily depend on one's own beliefs and perspective. Below are a few examples...
- Feeling one has two souls, with one of them being a Non-Human soul
- Feeling one's soul is shattered and made of fragmented parts, including a Non-Human shard (or multiple)
- Feeling one has been reincarnated
- Feeling one was rebirthed as a human for a higher purpose
- Feeling one has a misplaced Non-Human soul
- Feeling a connection of the soul between alternate realities
- Feeling an astral or cosmic connection
- Feeling a psychological disconnect with one's human being
And this is just the surface. Ultimately, the reasons are near limitless. But ensure that you are challenging your beliefs. Correlate your experiences with your belief, and be prepared to revise your theory if one of the variables has been debunked.

How does one know if they are Otherkin?

With time and patience! There isn't a test, psychological or biological that can prove you are Otherkin. One can feel they are Otherkin because they like to run on all fours, or maybe... they just like to run on all fours regardless.
The key is to be honest and open minded with yourself. The Otherkin journey is often lifelong, you'll make decisions, and change them. Personal identity is one of the hardest things you can figure out in life, nobody is born with a label stuck to their head. You have to discover yourself, through clues of introspection and practical experience.
Likewise, you cannot tell another person if they are Otherkin or not.

What are the signs that one is Otherkin?
It of course varies between individuals, but can also depend on the theory of one's kintype. For example, one may experience memories spanning from a time many centuries ago. But that would only be applicable for reincarnation or alternate realities. But here are a few examples of signs...
- Experiencing memories from a different body
- Feeling dysphoria over one's human body
- Feeling like you should be able to do things your human body can't
- Feeling phantom limbs not belonging to a human body, of which can cause phantom pain.
- Feeling older than one's biological age
- Missing a place that one cannot recall what or where it is
- Walking, sitting, or moving differently to accommodate a more non human form.
- Having ailments, mentally or physically that doctors can't seem to explain
- Seeing one's inner child as a hatchling or a pup.
- Feeling more at home when away from human civilization.
- Feeling one doesn't have the same mental/spiritual/social requirements as other humans
- Avoids playing/posing as a human when you can (such as in roleplaying/gaming/etc)
But having these signs doesn't necessarily mean you are Otherkin. Otherkin is an identity, not a list of checkboxes. Only you know if you are Otherkin or not.

Is it valid to not know what your kintype is?
Definitely. The definition of Otherkin only states that you don't feel human. It's okay to not know. You can simply refer to yourself as Otherkin, Therianthrope, or even a kintype from a general clade. As an example, acknowledging you are perhaps a feline but not sure which species in particular.

What if one changes their mind?
If you believe you are Otherkin, and then change your mind lately - that is perfectly okay. It does not mean you made a mistake, or wasted your time. Every step of self discovery is important and leads you closer to knowing yourself.
In regards to kintype specifics, it's understandable that one might realise they are more X than Y over time, especially if those two beings share a common set of features. There are many living species, beings in and outside of this world, and it would be very lucky to find your true kintype on the first guess.

What is the relationship between Otherkin, gender, and sexuality?
Being Otherkin doesn't change your sexuality or gender. Neither does gender or sexuality change you being Otherkin. However, they can have close relations with one another.
For example... An Otherkin may feel asexual because of the species gap between themselves and other humans.
Or an Otherkin may feel that their gender doesn't correspond with the human theory or understanding of gender.
In saying this, it is not acceptable to take part in sexual activities with animals. Regardless of your orientation, make sure each member can verbally consent.

What is the relationship between Otherkin and Furries?
They are two different communities, which one can be a part of both. Being a furry typically means to roleplay or act like an animal simply for leisure purposes, including dressing up as said animal(s). Whereas, being Otherkin is an involuntary condition, and does not necessarily dictate how you present yourself.
