The rabbits in Potter's stories are anthropomorphic and wear human clothes; Peter wears a jacket and shoes. Peter, his mother, Mrs. Josephine Rabbit, and his sisters,Flopsy, Mopsy, and Cotton-tail live in a rabbit hole that has a human kitchen, human furniture, and a shop where Mrs. Rabbit sells various items. Peter's relatives are cousin Benjamin Bunny and Benjamin's father Mr. Benjamin Bunny.
In The Tale of Benjamin Bunny, first published in 1904, Peter's cousin Benjamin Bunny brings him back to Mr. McGregor's garden and they retrieve the clothes Peter lost in The Tale of Peter Rabbit. But after they gather onions to give to Peter's mother, they are captured by Mr. McGregor's cat. Benjamin's father arrives and rescues them, but also reprimands Peter and Benjamin for going into the garden by whipping them with a switch. In this tale, Peter displays some trepidation about returning to the garden.
