My kid's cat is sick. About an hour ago, when I was coming down our stairs their was a HUGE pile of cat through up. It was brown and was heaped in a big pile. I cleaned it up and when I went in the other room there was 2 more areas of throw up but these were clear pools. When I found the cat he throwing clear liquid up again. He is walking very slowly and his stomach is heaving. When I looked in his eyes, his pupils were huge and his eyes look glassy. He keeps throwing up the clear liquid stuff and he just doesn't look right. Is there any ideas of what could be wrond? Is he just sick or should I be concerned. We live in a small town and there is no Vet clinic open at this time of night. Any suggestions would help greatly! Thanks!!
