Here's an old feud that's classic DL catnip. Betty White and Bob Barker, both prominent animal rights activists, apparently had a few rocky feuds over the years of their semi-friendship. The most public of these involved an elephant enclosure at the Los Angeles Zoo.
Betty believed zoos were essential to promoting conservation and education on wildlife issues. She supported the Zoo's plan to expand the elephant habitat.
Bob Barker believed zoos were abusive and should be closed, and he opposed the Zoo's plans.
This feud severed the friendship, according to this dated article from your grandma's favorite source of "real news."
Does anyone have any other information about their relationship over the decades? What's the world of chummy celebrities who love animals (call it "Bestie Bestiality") really like?
