Thumper is our house rabbit and is about 3-4 months old. Over the last month I've noticed that he seems to be clumsy. At first it seemed like if he stretched up on his hind legs, he'd fall over. But lately (maybe b/c I'm watching him closer??) it seems to be happening more. If he goes to clean his side or butt he falls over. Sometimes I hear a thump from his cage but sometimes he just rolls over. I've checked his ears as that was my first thought but they are clean and no mites. I haven't noticed a head tilt but he does lay on his side a little weird at times (picture below). Otherwise he seems fine. Do I just have a very ungraceful rabbit or is there something wrong with him? And if there's something wrong with him, what can I do for him without a vet visit? I run a home daycare and 2 of my 3 families moved this month so my income is currently a bit low.
