What's Rounder, Bunny's Front End or the Back End?

Thanks, Phoebe and bunny Star! Phoebe writes, “Star and I have recently moved house again (third time this year) and it's taken her a while to settle, but she has now identified her favourite spot for offering moral support while I'm working. I've sent a couple of photos so you can her loafing as well as her beautiful face, as whenever I try to take a photo from the front she has to get up to see what I'm up to!”
