Selected emerging diseases in ferrets.

Since their introduction as pets several decades ago, ferrets have become an increasingly popular household pet. Great strides have been made in improving their diet and understanding common diseases (eg, insulinoma, hyperadrenocorticism, lymphoma) that affect them. With the frequency with which these conditions are seen, it sometimes is easy to forget that ferrets can be affected by other diseases. Some of these diseases, such as cryptococcosis, are known, but may be increasing in incidence and range, whereas others, such as hypothyroidism and pure red cell aplasia, may be underrecognized or underreported. This review highlights new and emerging diseases not already well reviewed in the literature.
