LONE ROCK, Wis. (WLUK) -- When temperatures dropped, a small southern Wisconsin farm got creative to keep their calves warm.
WMTV reports the idea of "Moo Muffs" came after Holly Poad, owner of Triple P Farm in Lone Rock, lost her barn in a fire and had to find a way to avoid frostbite on newborn calves.
In addition to calf jackets, Poad and her aunt Kim Ewers, who owns an embroidery business, got together to come up with the perfect design and material for calf earmuffs.
"Moo Muffs" includes water-repellent material and fully adjustable straps.
Last month during the polar vortex, Poad decided to sell some pairs of "Moo Muffs" on Facebook for $20 a pair.
Poad says orders have come in from all around the upper Midwest, gaining national and international attention.
Because of the now growing demand for "Moo Muffs," Poad is working with a livestock supply company to produce them so she can concentrate on her farm.
