Bob Barker has always been an advocate for animal rights, from demanding that a zoo in North Carolina close their bear exhibit, to paying for an anti-whaling ship to rove the waters. And if you ever watched him conclude an episode of 'The Price is Right,' you know his opinion on spaying and neutering pets.

Now, the Associated Press reports that Barker has donated $2.5 million to the People for the Ethical Treatment of Animals (PETA) to help open a new location in Los Angeles.

He will have the honor of cutting the ribbon at the newly-named Bob Barker Building on Wednesday.
