Thanks Guys!
I swear, I never leave the vet w/o spending $200

lol.. he was due for rabies too and I usually just get them at the clinic near my house for $10 but since we were already there, just got it.
Anyway, vet did a Glaucoma Test which came back perfect. She said the numbers were good, whatever that means. She also did a corneal stain and looked into his eye in the dark, and did not see any scratches or anything on the eyes.
So she thinks it's just some kind of infection. His left eye was definitely kind of red when she lifted up his eye lids.
She gave me eye drops (that have a little pink top on them) and it says: 'Neomycin and Polymyxin B sulfate and dexamethasone Opthalmic Suspension'
She said to give them 2-3x a day and they usually work pretty fast but if it seems to get worse or not better, to stop them and call her immediately.
So *crosses fingers* hopefully the drops help!
