Gastric Ulcers Ferrets can get ulcers almost just like the kind people get. They can be caused by stress, both emotional and physical. Also ferrets can get ulcers from a bacteria similar to human H.pylori, H. mustelae. Although the name sounds frightening, these growths are benign. They look like scabs, but they do not go away like scabs do.
Surgical removal is the only available treatment.
This is the most common ferret malignancy and, unfortunately, is not curable.
