He's not been himself for over a week now. I first noticed that he wasn't eating properly and I hadn't seen him drink in a while. I took him to the vets and they told me that he was de-hydrated and to feed him water and vegetable baby food through a syringe, which I then did. After a few days he started drinking by himself and eating small amounts. His poos are not normal either, they are irregular shapes and very soft. Some days he's miserable and doesn't move much but others he is more himself. He is very skinny and is now 680g when he used to be over 1,000g and although eating he still appears to still be loosing weight. I will be taking him to the vets again as soon as possible but I'm not sure what to. Does anyone have any idea what could be wrong with him?
