Hello all, first time poster, second time rabbit owner! I recently adopted a rabbit from a shelter and he seems pretty healthy, he's been neutered, but I notice he has an odd habit while exploring. Occasionally he makes this strange moaning sound and I'm not sure what it is. What does it mean? Is this the so-called honking I've heard about? My last rabbit was very quiet, she never made a sound, at least not while exploring. Sometimes she would growl but that's besides the point, she never honked so I have no idea if this is what he is doing. He also thumps a lot while exploring, I dunno if this is normal, can someone tell me if it is? I know thumping can mean alarmed or afraid or even occasionally angry, so I hope he's not afraid or angry. Could it just be he's trying to get my attention? Anyway, any help that can be provided would be much appreciated, thank you!
