Hi. I'm new to this so I'm not really sure how it works, but I have a 8 month old bunny called Winnie. (Names after Winnie the Pooh) he is a very lively & curious bun and explores all of his new surroundings. He lives in my bedroom and I lock him up in his dog crate at night time, but apart from that he free roams arround my bedroom.i think something is up with him because yesterday he was running arround my bedroom doing binkys and laps arround my room all happily, and the next minute he thomps his back leg and goes into the corner of my room and starring at the wall for about 10 minutes, making grunting noices. I read somewhere that this is signs of stomach pains or something. But I'm not sure. He is eating loads of hay & pellets and pooping. I haven't really seen him drink much to be honest. But he might be. I'm concerned for him. I don't know if I should take him to the vets or just leave him. My mum thinks I shouldn't bother wasting the vets time as they have more important things to worry about. He has never acting like this before. Can somebody please give me some advice? Should I worry about him or is this just a faze. Thank you!!
