All of a sudden today, my 5 month old kitten ended up with what looks like an eye infection. He has Congenital Vestibular Disease so he's a little lop-sided but today his ear is all the way toward the floor (on the side of the bad eye). His eye is pretty much shut and when I try to open it, his pupil is in the corner and all I see is the pink inside his eye. He keeps rubbing it and rubbing it. My Vet never called me back and I called a 24-hr emergency vet but they charge too much for me to take him in today. Does anyone have an idea what it could be? He's an indoor cat, he's a Siamese and I'm worried if it's contagious.
