dilated pupil in cats one eye

by Carl
(Canada)

Hello,

I just noticed that our 14 year old male cat has a large pupil in the right eye and a smaller one in the left.When a light is shined on his eyes the large pupil doesn't dilate.Is something to be concerned about?
Thanks,C

Hi
yes this needs to be looked at by a vet urgently i think.
i am not a vet but this is certainly something which needs to be checked out sooner rather than later.
i would not like to give yo a diagnosis, theres nothing worse than trying to second guess and then worry someone without proof.

i would be very interested to know what the vet diagnosis.

i hope he will be Ok again soon
best wishes Kate

My cat has the same thing :-(

Has anyone had this diagnosed? I had all blood tests done and my cat is perfectly healthy. He is 15 and looks just like this picture. We think he had a stroke or seizure last week- found him on his side. He seemed fine except for his eye. At first it just looked weird, but now he isn't himself and I think he is in pain. Seems like might be a brain tumor. :-(

Same as my CAt!

Hey there
came across your page when looking for information about the same thing happening to my cat!

his pupil went tiny and the other dialated after he got in a fight with the big bad cat who comes in our cat door and attacks him :( for his food
it is now back to normal but i am taking him to the vet tomorrow night.. he also has a massive lump on his chest i think is a cyst from the other cat hurting him
my cat is only a baby at 1 year old.

hopefully all is well.. will update you tomorrow.

did you hear anythign back about ur cat and his eye??

regards,

jess

Hi
I really hope your cat is now doing really well. I happened to come across your page looking for information about this very particular topic since I just discovered this on my own cat (Tigger) who looks just like yours!
I was hoping that you could let me know what you learned from your visit to the vet since I'm taking Tigger to his in the morning.
Thanks so much and best wishes
Sincerely,
Claudia

Regarding the one enlarged pupil
by: Catherine

I hate to bear bad news but this happened to my 10 year old cat. It was an early sign of a brain tumour and I had to put the cat down before he was in any pain. He had congestion accompanying the dilated eye as well so he was not comfotable.
