On Tuesday night I knew something was wrong with him as he was randomly sitting on shelf which he doesn't do I went over to check on him and he started making an effort to walk but his whole body was jerky I tried giving him something to eat but he tried but seemed to takes ages trying to eat one small piece of food I didn't think he'd make it during the night but come the morning he had perked up and running about I assumed he was OK I then went to work returned him and he was lying on top of his bedding which is weird for him he prefers being under it I thought he was gone but he was struggling for breath taking shallow breaths every so often he'd try to perk up but couldn't he had no strength he passed away shortly after but haven't a clue what was wrong he also had a thing for the last two or three weeks which I don't know is relevant where he'd run round his cage in circles which he never did before I just put it down to him being hper but now don't know if this was a health issue does anybody know what was wrong I now feel guilty about not taking him to vet yesterday morning maybe if I had done he could have been ok
