Help me eliminate allergies?

Cassie has been having some problems with her left eye, and only her left eye.

It's been on and off, and not constant. Mostly at nights. Her eyelids would become red and she'd squint that one eye.. It does not happen all day, and on most nights before bed, and in the mornings it looks completely normal. I noticed a small greenish discharge few days ago, but nothing more after that.

I am thinking it's allergies since it's not consistent enough to be pink eye or anything.

Can some people list some possible suggestions that may be causing allergies? I'd like to try to figure this out. The only one I can think of is the litter.

If it was allergies why would only one eye be affected? 

Airborne allergens.  'nuff said!  LOL  If your weather is changing or the wind is blowing, it very well could be airborne allergens.  It can affect one eye more than the other.  You can try adding Lysine to their wet food and see if that helps.  I give my herpes girl an antihistamine daily (1/4 to 1/2 of a 10 mg Claritin/loratadine) and it really helps her with sneezing, eye irritation, and itchiness.

I would think a cold would affect both eyes? And pink eye is more constant.

I can try lysine again. My poor girl, between the virus she had, pink eye, ringworm above her eye... She can't get a break!

When I worked in the shelter I knew a kitty who caught an upper respiratory infection (cold) and it caused only one of her eyes to partially close with a bit of discharge and after she got better it went back to normal. If you have any other cats that have had URI's they can spread to your other cats when their immune system gets weak.

Does she sneeze or have discharge coming from her nose too?

I ended up adopting her, coincedently. Here's what it looked like. It stayed this way for a few weeks and then reverted back to normal.

She's a cutie!!!

No other symptoms. No sneezing or discharge or anything. Just a red squinting eye on occasion

I've never met someone who gets hayfever in just one eye..

I have one kitty that feline herpes and 2 others that don't.  They ALL favor one eye more than the other when irritated.  I have eye allergies as does my husband.  His right eye is usually the eye to be affected worse.  My left eye seems to always be the one that reacts to allergens.

I don't think it's feline herpes, since it's not watery and not gunky (other than usual sleep gunk). The eye looks normal, other than reddened lids that flares every so often. Herpes is more consistent, right?

Not really.  I don't think it's herpes because it usually presents with other symptoms, too.  I really think it's just irritation from airborne allergens or even dust if you've vacuumed recently.

Last night, after self grooming, I noticed Cassie's eye were a bit more red than usual and teary. Then a bit later, green gunk at the corner of her eyes. I still have eye ointment from when she had pink eye and put it. I gave her Lysine last night and this morning.

This morning, her eye looked almost perfectly fine, just slight squinting, but normal other wise and gunk-free. I'll see tonight.
