Went from being normal by appearances to sleeping long periods of time,eyes looking off to the side, barely eating or drinking, to hiding. The vet did blood work, xray, etc,...There was no diagnosis, just one hundred possibilities. Recommended that we see a neurologist. Only one is in Portland, 3 hours away. We also noticed after the vet visit that his right eye was half open and irritated. Now, that eye is no longer blue but yellowish orange. He is a flame tip siamese , 7 yrs of age, adopted from the shelter when he was 6 months old. He had symptoms of asthma when we adopted him. I am trying to think o anything that would be important.
