I currently have a 5-6 year old female, who over the past 6 months to a year has been exhibiting signs of insulinoma. Over this time period though, the symptoms have been sporadic. Are there any documented cases, or has anyone ever heard of a ferret having insulinoma symptoms sporadically like this? I am just curious.
