Bunnies
The Bunny Museum
Twenty-some years ago, Candace Frazee and Steve Lubanski began exchanging daily rabbit-related gifts. This continued until the collection grew to the point that they joked about living in a bunny museum. In 1998, they made it official and opened the Bunny Museum in Pasadena. The museum recently moved north to Altadena and the collection contains over 35,000 bunnies.
If you can charge an admission fee, it's not hoarding; it's a museum.
