I'm not sure how it works but he was showing extreme outward signs of a neurological problem with his movements and loss of a sense of direction and she said that in order for him to be in such a debilitated state it had to have been going on for months and considering he was at most six months old we think he was born with it and that it didn't suddenly develop. Other signs was that he refused to eat as much as he should have been, was completely uninterested in food and by the time we took him to the vet he was anemic and severely emaciated even though we tried many times to get him to eat.
