PETA President Ingrid E. Newkirk says Barker could have just given the group a refrigerator but instead he paid for an entire building to be renovated.
The building will be home to the group's media, marketing, youth outreach and campaign departments.
The 86-year-old Barker delivered his spay and neuter message on "The Price Is Right" for a quarter century. Since he retired in June of 2008, he has taken his activism on the road, promoting freedom for whales, an end to the fur trade and other causes.
