Viral photos of deer with strange warts follow 'Frankenstein' rabbit, squirrel sightings

A rare albino deer was spotted enjoying a midnight snack from a bird feeder in a suburb of St Louis, Missouri. Albinism is observed in one in 30,000 deer, with albino deer referred to as "ghost deer," according to the Missouri Dept. of Conservation. As photos of so-called "Frankenstein" rabbits and squirrels with strange growths on their heads and bodies have started to pop up on social media, users are now sharing pictures taken of deer with bulbous warts. While the warts, or "fibromas" as they're called, may look scary, they generally don't affect the deer's health unless the growths are around the eyes and mouth, hindering their ability to see and eat and making it harder to move, according to experts. Deer fibromas are caused by an infection and are common in the U.S., the Maine Department of Inland Fisheries and Wildlife says on its website, adding that similar diseases affect squirrels and rabbits.
