Moose warts ugly but benign

The good news is that this is a benign disease with no discernible health risk to the moose.

The bad news is that these unattractive moose won't make the cover of Alaska magazine.

These moose have benign epithelial tumors, or papillomas. In common terms, they have warts.

Papillomas are fairly common in domestic and wild animals. The warts can be 1 to 6 inches wide and can be found throughout the body, head and legs of the moose. Lesions tend to regress over time and will usually disappear within a couple of years. Papillomas are caused by viruses and spread by direct contact. Humans cannot get warts from infected moose.

Another unrelated disease, called "sleigh hoof," is commonly seen in moose around the lower Kenai Peninsula. This disease results in long, curly hooves due to faulty keratinization. It is believed that the abnormal hoof growth is caused by a copper deficiency. While it looks uncomfortable and likely does not make life easy, moose with sleigh hoof survive and can live a long life.
