Hi, I am having trouble figuring out why my rabbit is making strange noises. I tried looking at other topics, but couldn’t find anything that described the same variety of sounds that my rabbit is making. He didn’t used to make many sounds, but he is now making a lot of sounds daily. He isn’t making sounds all of the time, but it seems to be happening every time I give him food, pet him, or pick him up. He also makes the sounds randomly while resting sometimes. The noises almost sound like he is congested, but there is no discharge from his nose or eyes. The noises are sometimes soft when he is breathing calmly. The sometimes sound like a loud honk randomly, unprovoked. Also, the sounds are like a high pitched repetitive squeak when I pick him up to give him his medicine. I have brought him to the vet (a small animal, exotics vet), and the vet said he did not know what was wrong. This veterinarian seems to be knowledgeable of rabbits, and comes highly recommended from the local animal hospital. He gave him an x-ray, and said at least the rabbit does not have pneumonia. He did not think that the rabbit had snuffles, but put him on an antibiotic anyways. He has been on the antibiotic for 2 weeks, and the noises have not lessened. He eats, drinks, urinates, and defecates as usual, and his activity is also normal. It sometimes seems like he may be breathing hard, but I am not sure if that is just because I am paying more attention to his breathing now. The rabbit is 4 years old and otherwise healthy. If you have any information that might help, or have any ideas of what may be wrong, please let me know. I am very worried about my rabbit, and want to do whatever I need to help him.
Here is a youtube link of him making some of the sounds: https://youtu.be/o2ApzFwag4w
Thank you so much for your time.
