Hi, every 2 - 3 days my 10 year old rabbit goes of her food, refuses everything including treats, veg, grass etc. She sits doing the rabbit press ups, breathing very quickly looking sad and does the occasional squeak. This lasts 4-6 hours and then she is suddenly fine! I thought maybe she has arthritis so has had metacam every day for a few weeks but it hasn't made any difference. Anyone got any ideas?? I have not changed her diet or anything, she is in the same room of the house, no changes have happened... vets haven't really helped, they just say shes old and that I need to consider letting her go... but she's fine majority of the time! Even binkys....
