I can only see 1/4 of my cat right eye pupil

My cat Mickeys right eye has been making me scared. Her right eyes pupil has been turned to the top of her eye and only 1/4 of her pupil can be seen. I am scared that my cat could have injured her eye from bumping somewhere. Can anyone plz help. 

For this situation, I would suggest getting her in to see a Vet as soon as possible.  The eyes are nothing to mess around with. 

This is definitely not something to just hope it will go away.

It must be examined by a professional.

Causes of unequal pupils can be a feline leukemia infection, an infection (bacterial, fungal or viral) or inflammation in her eye, trauma, a tumor in her eye or along the pathways of the nerves that innervate her eye,  glaucoma, feline infectious peritonitis,toxoplasmosis, a polyp in his nose or pharynx, or idiopathic meaning we never figure out why it happens. Of course treatment depends upon what is causing the problem.

If she has a droopy eyelid and her third eyelid is raised on the side with the small pupil it's likely she has Horner's Syndrome and that is the affected eye. This can be from a middle ear infection, a polyp in hers ear creating pressure on the nerve to her eye, a feline leukemia infection, a intervertebral disc that's displaced and affecting nerve function, a tumor or a fibrocartilagenous emboli leading to nerve damage or idiopathic.

Is her pupil not showing because her eyelid is drooping?
