If it smells like pee at Cheyenne Frontier Days, it might not be the animals. The Cheyenne Police Department posted a picture on Facebook this weekend with a catheter bag they found near Frontier Park.

"122 years of CFD results in a few unwanted items being randomly discarded where they don't belong," the post read. "We're used to the calls of cans, cups, and cars in people's yards, but (this) may be a first."

Rookie officer Vielhak was dispatched to dispose of the disgusting item. Adding insult to injury, it was his birthday. What a thoughtful present.
