Huh, for some reason I never thought of that. No, I haven't brought him to the vet, and right now I'm not going to. My family may be moving soon, so it's an expense we probably don't want to pay for, and I know if he is any discomfort or pain it is minimal, because he acts totally fine and it calms down after a while. I'll research allergies and see what comes up, perhaps I could even find some answers or medicine I could buy or make myself. Dunno, since I've never had to deal with it.Sounds like he could have allergies.
Have you brought the bunny to the vet? They could probably recommend some type of allergy medication that will help.
Thank you for the reply!
