My cat's eye isn't getting better; why aren't her drops working?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 8 lbs

Good day, I have a cat I took in from outside and have been to 4 vets wanting them to check one of her eyes and have been told to give her neomycin and polymyxin b sulfate suspension drops but with no sign of improvement, & they dont act like its a big deal she keeps in closed sometimes and my husband won't let me spend any more money on my concerns, she had lots of problems initially with worms & that is taken care of now, any advice I would greatly appreciate,

Hi there and thank you for using Pet Coach! I am sorry you have been to multiple veterinarians with no resolution. Unfortunately, this can happen with many diseases and health problems as they don't always respond to our recommended treatment. From the pictures you provided, it does not appear to be a condition that would respond to a eye medication. What this looks like to me is either a pigmentary change to the iris or an eye tumor such as an iris melanoma. I would recommend a workup by a veterinary ophthalmologist for a second opinion. Unfortunately, if you are unable to work him up further, there is not much you can do at home for an eye tumor as these need to be surgically removed or the eye needs to be removed. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns.
