Magical Menagerie

A very crowded pet store, noisy with the sounds of all the animals, where Hermione bought Crookshanks. The proprietor is a witch who wears heavy black spectacles. She offers advice and sells things like rat tonic. Other creatures for sale included:

enormous purple toads
gigantic tortoise with jewel-encrusted shell
poisonous orange snails
a fat white rabbit that changed into a top hat and back
cats of every color
noisy cage of ravens
custard-colored furballs
sleek, black rats, rather more intelligent than normal
