To Christine Staab, whose ferret has a head tilt - The history of an infection which has resolved following antibiotics and a residual head tilt is strongly suggestive of an ear infection. There are nerves in the ear which affect balance, even how the head is held. Generally the side that the head is tilted to and the animal falls to is the side that has the infection. Another, more remote possibility is that of a tumor either in those nerves or in the brain. My suggestion is to continue the antibiotic for 3-4 weeks and also to use a low dose of prednisone or cortisone on top of it. You must have the animal on antibiotics and the dose of cortisone should be low, or you may worsen the infection. I can't predict whether you will see improvement or not. Many of the cases improve, some even are cured, but some also show no improvement. In the case of a tumor, there isn't a lot you can do. Best of luck - keep us posted.
