Nugent and the animal rights movement have long had an adversarial relationship. In 2000, Bhaskar Sinha was jailed briefly following an incident with Nugent outside a department store in San Francisco in which he allegedly threatened and physically assaulted Nugent, who in turn took Sinha into custody until San Francisco Police arrived and arrested the protester.
Nugent has reported receiving death threats against him and his family from animal rights activists. On the Penn & Teller’s Bullshit! episode about PETA, Nugent claimed, “We’ve got reports and files with law enforcement across America where animal rights extremists are on record threatening to kill my children on the way to school because we eat pheasant”. In 2006 he stated in an interview that “anyone who thinks hunting is terrible can kiss my ass.” 
In a 1992 radio interview, Nugent referred to Heidi Prescott of the Fund for Animals as a “worthless whore” and a “shallow slut,” asking “who needs to club a seal, when you can club Heidi?” and was ordered by a court to pay $75,000. 
Nugent owns a hunting ranch near Jackson, Michigan, called Sunrize Acres. Anti hunters claim this fenced facility offers “canned” hunts. Nugent has said, “I understand the criticism” from those who say canned hunting violates the ethic of fair chase, though he still operates the facility. Nugent was recently interviewed by Field & Stream magazine regarding “canned” hunts. At Sunrize Acres he personally guides customers on a hunt for trophy bull bison ($5,000), Russian boar, or white-tailed deer ($10,000 each).
