Cat Squinting Right Eye?

[FWFishLover]

my black cat's right eye is squinted....
no discharge...so what could it be?

He probably just has a hair or something in it. My cat does this occasionally too. It should work it's way out on its own, but if he's still doing it in a day or so, then consider taking him to the vet to be sure he hasn't injured it.
