my cat has a little "clear flap" near her eyelid she also had clear discharge?

I had to keep her in the kitchen for a couple of days to separate my two cats they fight a lot... I come home and a bunch of things are knocked down. she was trying to get to the window probably. My vet isn't open tomorrow. they will be monday. I don't think it's very serious. it could be I only been gone since Friday at 2 oclock. and I just got back. I might try and wipe it up with a q-tip or something else.

But some answers now or by tomorrow would be great. She is eating just fine, and drinking water. and shes responsive. I don't think its much but she is squinting. I think she probably hit her eye :(

my parents doubtfully will take me her to an emergency hospital, especially with the snow.

if it is that serious I could probably tomorrow morning to an emergency place. thank you. im thinking she probably bumped her eye. Ive read it is serious especially involving the eye. but hopefully it will be better by tomorrow
