I remember this back in the 1980s in Miami, regarding Santería.
Ahh, Church of the Lukumi Babalu Aye v. City of Hialeah - https://en.wikipedia.org/wiki/Church_of_the_Lukumi_Babalu_Ay... .
Basically, the Hialeah City Council thought Santería practices were un-American, un-Cuban, and "abhorrent to its citizens", so banned "sacrifices of animals for any type of ritual", but made sure to allow: "Kosher slaughterhouses, regular slaughterhouses, hunting, fishing, pest extermination, euthanasia of stray animals, and feeding live rabbits to greyhounds."
The Santería church sued, and in 1993 the Supreme Court "concluded that the city's ordinances violated the Free Exercise Clause of the United States Constitution."
The Wikipedia entry also points to the more recent Merced v. Kasson from 2009, where the judge ruled the Texas Religious Freedom Restoration Act meant that the city's prohibition on the slaughter of four-legged animals "substantially burden plaintiff's free exercise of religion without advancing a compelling governmental interest using the least restrictive means."
> ... Somewhat similarly in 2009, a freedom of religion case related to animal sacrifice was taken to the U.S. Court of Appeals for the Fifth Circuit in the case of Merced v. Kasson ... The court ruled that the ordinances "substantially burden plaintiff's free exercise of religion without advancing a compelling governmental interest using the least restrictive means", as required by the Texas Religious Freedom Restoration Act.
