My old cat's pupils are dilated. Is she blind or near her last days?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | 19 years and 6 months old | 7 lbs

she is outdoor, 19 yrs. Deaf, but does fine. Now her pupils are "almost always" dilated, so she acts blind and fearful. Is she near her last days?

I would recommend taking her to a vet for some basic blood work. It is very common for older cats to get hyperthyroidism. This is where the thyroid over produces and will cause their blood pressure to go up. High blood pressure can lead to retinal detachment which will cause dilated pupils and issues with vision. I think it is also possible she is losing vision as she is getting older. However the blood work with her age would be helpful
