My cat has misshapen uneven pupils

I noticed a few months ago that my cats pupils are uneven and misshapen. He is a stray who I met as a kitten and has been fed by me and stays near my house since. Unfortunately I am still a teenager living at home and do not have the means to take him to the vet and so he has never been. He is not in any pain and has not acted unusual, the only thing that has changed are his pupils. I believe he is around 1.5-2 years old. I would appreciate any advice or suggestions on what could be  happening.

Hello. I'm afraid that animals with uneven pupils really do need to visit the vet.  All animals have to go to the vets for the first time one day, but that is no reason to avoid it, especially as this may turn out to be an emergency.  It suggests that either the nerves in the brain controlling pupil size have been obstructed on one side but not the other (eg because of a lump, obstruction or swelling somewhere inside).  Alternatively there could be a lump, swelling or irregularity originating inside the eye eg a badly placed uveal cyst or tumour.   In general these cases tend to be emergencies so please do speak to your vet directly.

(I hear that your cat has been fine until now, so this case may wait another day - your vet will advise).

Other possibilities may include adhesions from when the eye was formed, or secondary to some underlying kittenhood virus.   Sometimes, your vet will be able to tell you more by viewing the eye from the side.  Whatever they find, I would be interested to know; please will you update us once your have seen your vet?

I took him to my local vet today. The vet did not look at him as he was very stressed so they kept him in the carrier. I showed him the photo of his eyes (same photo I uploaded originally) and he said he probably just bumped his head and that if he can see he is fine. The vet did not spend more than 2 minutes with us before dismissing and he did actually examine my cat. Should I get a second opinion?

*did not actually examine

Hello!  Your vet has obviously now seen more of your cats' eyes than I have myself.  It sounds, however, as though you were dissatisfied with your consultation today.  In any situation where you do not feel that an adequate examination has been carried out, you should always talk this through with your vet.   After all, they are your vet and accountable for their service.  I personally like it when a client asks for a second opinion because if I am wrong, I will learn something and if I am correct, it will restore the client's faith in my opinion.  How satisfied are they that your cats' pupil is not a cause for concern / what is signified by the difference between the eyes?  This is often a question worth asking; you could always ask them to document the answer.
