Just had a bit of a scare with my bunny, thought he was dying but now seems okay. He was making loads of noise upstairs, came up to find him continually running fast around in circles. He stopped when I went up to him, but was breathing really fast and just wanted to be left alone, then when I went away again he again started doing the same thing. I picked him up, brought him downstairs and he was acting a bit strange like he wasn't quite with it, but a few minutes later he was fine again, wanting attention and taking a treat. Just wondered if anyone had any idea what was wrong with him because it was quite scary, could it have been something in his ear, a fit or maybe because he was too hot (he'd been upstairs all day where it is hotter than downstairs)?
