The libertarian Cato Institute, known for its irreverent, sometimes funny, U.S. Supreme Court briefs, has just aimed its provocative writing at prairie dogs. They can only bark back.

The Cato Institute filed an amicus brief to bolster the case of more than 200 Utah property owners who are challenging the federal government’s regulations protecting the Utah prairie dog under the Endangered Species Act. The animals, numbering about 40,000, are found most often in southwest Utah where, according to the petitioners, they wreak havoc by burrowing and digging holes on private property, public parks, airports, golf courses and cemeteries.
