The Columbia Basin Pigmy Rabbit is the smallest and perhaps the rarest rabbit breed in the world. It is native to just one part of the Washington State Area, and weighs under 500 grams.
There are plenty of tiny domestic rabbit breeds to choose from if you’re looking for an adorable pet rabbit, but the tiniest of them all is actually a wild breed that doesn’t make a great pet. The Columbia Basin Pigmy Rabbit is skittish and nervous, but the main reason why you’ll most likely never own one is its critically endangered status. The breed was declared extinct in the wild in 2001, when the last 14 specimens were scooped up from their native habitat and put into a captive breeding program.
