I have a 9 month old male orange tabby. When I got him he had a chest cold which turned into pneumonia in 3 days then was covered in ring worm from head to tail for 3 months. During the pneumonia he had his first "episode" of not being able to walk, screamng and hissing dilated pupils. (He is normally nonverbal and only chirps.) I witnissed the beginning of one episode where he was flopping on the floor and screaming. I picked him up and he was completely rigid. NO incontinence, foaming at the mouth or drooling. He hasn't been able to walk for 3 days. NO balance and his back legs just arent working. eating and drinking and litter box use fine. Blood work fine, and has tested negative for everything else.THis is his third "episode" and each one gets worse and the recovery time is longer. We have been giving him an anti inflammotory pain killer type stuff which seems to help a little. Im stumped and so is my vet. Can anyone help me?
