Those to be used for breeding should use the hormone HCG for taking them out of heat during cycles when they will not be bred. The use of vasectomized males can sometimes be unreliable, and we do not recommend it. C. Anal Gland Impaction Caused when the animal has a blockage to the outflow of anal gland secretion or abnormally thick anal gland material. Signs are few, doesn't seem to cause them much pain. If the gland ruptures, a draining hole will be seen near the anus, and the pet may lick at the area frequently.
Treatment is by surgical removal of the anal glands.
Even if only one is affected now, remove both as the other may become affected later. There is no prevention, and this disease does not occur with sufficient frequency to warrant routine anal gland removal in all ferrets. D. Cataracts Caused when the lens of the eye becomes opaque. Light can no longer reach the retina and the animal becomes blind. In ferrets it is primarily seen in animals under one year of age and is considered to be hereditary.
