She has been sleeping most of the day and has hardly moved at all. She has eaten a bit of hay and a few pellets and she had some greens this morning but there is definitely something not right. When she was out on the grass she just lay down and wasn't munching away like usual. She has recently lost some weight but when the vet saw her last week he couldn't find anything wrong like teeth or masses or anything. I tried to get her an appointment this evening but there weren't any so have got one for 10.50 tommorrow. I have bought her and Humpty inside for tonight so she son't get cold and I can keep an eye on her. I've given her a good look over and can't find anything obviously wrong Just feel so worried and don't know what else to do/look for.
