The objective of this study was to collect epidemiological data on neoplasms in pet ferrets in Japan. A questionnaire to collect information was made available to Japanese veterinary practitioners through the web site of the Japanese Society of Exotic Pet Medicine. Completed questionnaires were returned from 29 practices, and 945 neoplasms met the criteria for inclusion in the study. Neoplasms were found in every organ system except the respiratory system; the endocrine (418; 44.2%), integumentary (196; 20.7%) and hemolymphatic (184; 19.5%) systems were most commonly affected. The most common tumor types were pancreatic islet cell tumor (211: 22.3%), adrenal gland tumor (207; 21.9%) and lymphoma (152; 16.1%). The age of the affected ferrets ranged from less than 3 months to more than 7 years of age. Tumor incidence was highest in ferrets between 4 and 6 years of age. No sex predilection was found. These results were similar to those recently published in North America. Most Japanese pet ferrets are imported from North America, and their husbandry including diets is similar to that in North America, which may explain the similar tendencies in the incidence of neoplasms in this study and those of findings in North America.

Adrenal diseases are quite common in Japanese pet ferrets; however, there have been no reports concerning the epidemiology of ferret adrenal disease in Japan. The purpose of this study was to collect epidemiological data on ferret adrenal disease in Japan by sending a questionnaire to veterinarians throughout Japan. Among the 521 cases that met the criteria for this study, 307 were adrenocortical carcinoma (58.9%), 117 were adrenocortical adenoma (22.5%) and 87 were adrenocortical hyperplasia (16.7%), respectively. Sex, clinical signs, concurrent diseases, age and the sites of the affected adrenal gland in these cases were similar to those reported in North America. Most pet ferrets in Japan are imported from North America, and their husbandry in Japan is similar to that in North America, which may be the cause of the similarity in ferret adrenal disease between North America and Japan. Because a difference in the incidence of ferret adrenal diseases among countries has been reported, further research is necessary to investigate the factors related to the similarities and how to decrease the incidence of adrenal diseases in ferrets in Japan.
