white of the eye covering the pupil

Our pet cat eyes seem to show hardly any pupil in both eyes.both eyes are or looks to be covered with a white film.we have other pet cats that have had this & it took about 2 to 3 weeks for this to clear up.all our cats are special but this one is strictly a house cat & very special to us.
Thanks for any advice.

It's sounds like it could be cataracts? If you say it's cleared up in your other cats, though, I have no idea. I would check it out with your vet.

Does your cat seem to be having eyesight difficulties?

My first thought was the third eyelid. If that is what is showing, then that is an indication the cat is sick.

I'd suggest a vet visit as soon as you can get one.
