i just got home from work and my red eye is extremely sick and now all of the vets near me are closed. his eye is completely black and closed and he is not opening his good eye at all, except when he goes through, what looks to be, a seizure, where he jumps and flails his legs and then curls back up again. im not quite sure how to help him and if he is beyon help at this point. i would greatly appreciate any advice ASAP, thanks
