well i've just got back and they're going to keep him in over night under observation with regular feeds and everything and make sure that everything is working, even with me feeding him and feeding him water hes still managed to loose 2lbs,they think that it is his teeth and they are going to do it tomorrow but the said it might be something more serious than that givern that hes 4 and a half. I'm just so worried about him right now. Ill keep you up-dated on what happens over-night, thank you so much for all of your help x
