For someone who doesn’t want to use chemicals, dmso is a rather nasty one, it is great for certain purposes because it carries other medications into inflamed tissue but this also means it helps bring lots of unintended stuff into the skin or tissue as well and should be used with caution, especially on rabbits and birds. Also, even water is a chemical, so enough with the ‘all natural, chemical free’ jargon, you yourself are one giant chemistry lab, every living organism is, and all those essential oils and natural remedies are also chemicals, penicillin is derived from a mold, it has just been isolated by a lab and sold as a pure isolate. It is one thing to treat a mild problem without medical oversight or with basic stuff around the house, it is quite another to deprive an animal of proper treatment and make it suffer through a terrible illness because you are morally opposed to penicillin or whatever, humane euthanasia would be a far better option for the animal, sorry about this little soap box but I once treated a beautiful little Jersey cow, or she should have been, but she was miserable, peeing pus, and skin and bones, she was suffering for months and because she was an organic cow she couldn’t be treated with antibiotics. Finally the farmer let me treat her, she was now a regular cow, but she wasn’t at deaths door over a stupid man made rule, it was a kidney infection and very responsive to proper treatment but it was withheld for red tape. We need to do the best and right thing for the animals in our care, regardless of our preferences and opinions, I’m not saying spend thousands on something but if there is a reasonable treatment available withholding it is cruel. Head tilt can be a sign of inner ear issues but also neurological problems. Cats have an idiopathic version that clears up in a couple weeks with no known cause or treatment. Inner ear infection, either from external ear infection or spread from the blood is a possibility. Some sort of mass or tumor pressing on the area is another option. Stroke or head trauma is on the list. In rabbits I would also consider Pasteurella, it is more famous as sniffles but could easily cause inner ear issues, a course of baytril/enroflaxacin wouldn’t be a bad idea. Never use penicillin or amoxicillin orally in rabbits. If it is an inner ear infection treating topically isn’t going to touch it. I can’t recommend pouring anything into a rabbit ear with a possibly ruptured ear drum, especially dmso, it is right next door to the brain and bunnies are very sensitive critters. I also wouldn’t take medical advice from AI, while it can be helpful in many cases, it can be disastrous because it doesn’t vet the information whether it is true or reliable or even real, I just read a great article on people using AI to plan vacations and ending up trapped on a mountain overnight or paying lots of money to visit a place that doesn’t exist, but the AI can’t be wrong, I’d hate to have 5is happen in a medical case!
