I would appreciate your advice here please. My bun is 7 years and 8 months she is a house bun. During the last 2 weeks she has stopped eating her pellets. She was still eating her hay and her greens but she seemed to get weaker and kept flopping down. I took her to my vets on Mon she examined her and said her stomach was soft so no bockages. Her teeth were find and her hest was clear. She said she thought there was a bit of arthritis in her back legs and that's why she is lying down so she does not put weight on them. She gave her an injection (painkiller) and told me to give her 0.1 of metacalm every day for 4 days. Now she is hardly eating, still drinking, she feels colder and is just lying in her cage athough she nibbles celery when offered and a tiny bit of carrot I am worried!
