My roommate and I take care of eight rescued rabbits from various shelters in our area. As you can imagine, we've seen our share of illness and injury with these guys. One of our older rabbits, Hazel, is around 5 years old and has been sick, on and off, ever since we adopted her. She sneezes, has white discharge from her nose, and sounds congested when she breathes. I've taken her to a very good rabbit vet several times and she's been on various medications including baytril, injectable penicillin, and azithromycin. I've been told that some rabbits just don't ever shake this thing and that she'll probably have episodes like this for the rest of her life. I'm wondering if there is anything I can do to make her more comfortable while she's sick? She sounds terrible and she probably feels awful, I know I do when I have a cold... I started her the azithromycin again to try and knock this out, but is there something else that can be done? Would a humidifier help?
