There's nothing actually wrong with Meep's eyes, at her last physical they tested her vision and looked at her eyes, but I've noticed a curious thing:
One eye appears darker than the other in certain light (always the same eye) - is it possible for the tapus luteum (sp? the reflective bit that gives cats their night vision) to, well, become less reflective with age? She's 13.

I have no idea about deterioration of the reflectiveness. I think there is a good probability that the eyes are different from birth. Or the difference in darkness could indicate a disorder in the eye or normal aging. You could call your vet and ask him/her about it.

It's possible she might have a cataract in one eye. Do you have an animal eye specialist you could call?

Our vet is excellent. If there was a cataract she'd have seen it when she examined Meep's eyes at her last physical - two months ago, I think.

As another poster suggested, I suppose it could have always been this way and I really just didn't notice. It really just looks like it's the way the light falls, until one day I realized the light was falling wrong for the effect I see.
I'll mention it at her next vet check, of course, but I'm not really concerned. Just curious.

Why not call your vet instead of waiting until the next scheduled exam. If this sounds like a problem, your vet can ask you to bring Meep in for an appointment. If this is normal and not indicative of a problem, that would be a relief. But either way, it would be good to know. http://www.justanswer.com/questions/2duzd-cat-one-eye-continues-darker

I would like to say that over the years you have been posting in this group, I think Meep may be one of the most examined cats around. Emotion: smile If she has a pimple you don't know about I would be surprised. And that of course is a good thing. She has probably learned to make one pupil larger than the other just to get your attention.

Well, because her next appointment is in only a couple of weeks, to get blood tests because she was recently put on metacam. Vet trips stress her, when she stresses she gets cystitis, which usually means a vet visit...

Oh, that makes sense. I didn't realize the next appointment would be so soon. Please update us. (I am always particularly interested in anything that involves the eyes because of Duffy.)
