My bunny, who’s almost 8 years old, has been having some problems with his arthritis today and he seems like he might be in pain. I heard that chamomile can help relieve pain, so I mixed some with water and mashed up pellets to give to him. When I let him drink it, he made some weird noises that sounded like gulping/stomach noises that I haven’t really heard him make before. Upon further inspection, he’s doing this with his water but a lot quieter and not on every sip. Was he just drinking too fast before because he was excited about the pellets, or is this something I should be concerned about?
