Xenofiction

Writing fiction is an amazing exercise in stepping out of one's usual mental patterns and inhabiting the viewpoint of someone utterly different from ourselves. We write characters who come from different time periods, genders, races, religions, nationalities, native languages...and other species.
Xenofiction is any story from the point of view of a non-human character. This could be an alien, or a species native to Earth as we know it, or a fantasy animal of some kind, or an object*. Switching out of the human mindset opens up infinite possibilities for original and thought-provoking stories. 
Getting immersed in a non-human consciousness is hard work. It challenges our fundamental assumptions about things as basic as our senses and the way we construct thoughts. My recommendation is to put in a lot of research into your chosen PoV species, or do a lot of worldbuilding if it's a fantasy or alien creature. Obviously, you can't interview a sea serpent or an intelligent amoebae from Europa or even a housecat. But you can figure out things about your creature which allow you to make logical speculations about how it's mind works. It will also allow you to develop the character's values and conflicts. 
Go ahead and have fun. The more effort you put into this bit the more convincing and intriguing your character will be. 
*Fiction starring inanimate objects--called 'It Narratives' in literary scholarship-- started appearing and gaining popularity in the mid- to late-18th century, not coincidentally as the debate over slavery meant the public was caught up in discussion over what makes someone human.
