Hopefully I'm not butchering the breed standard when I say this, but at least from my perspective they seem more athletic because of the arched backs. The arch in turn brings their belly higher off the ground which gives them a tendency to look sleeker and more refined as opposed to the fluffy ball that a lot of other bunnies can look likeTans are so pretty! Their fur is sleek and shiny, really shows off those rich colors of theirs. I love this breed, they seem to have a more athletic look to them, moreso than your standard pet rabbits. Wonder what it is about them that makes me think that, hehe.
