pets in the Wizarding world usually showed some “interesting powers” and lived longer than Muggle animals (GF4); there were two magical pet stores in Diagon Alley: Eeylops Owl Emporium , where Hagrid bought Hedwig for Harry's eleventh birthday, and the Magical Menagerie, where Hermione bought Crookshanks (SS5, PA4); Hogwarts students were allowed to have an owl, a cat, or a toad, but this rule doesn't seem to be strictly enforced; Percy and Ron had Scabbers, the rat, and Lee Jordan had a giant tarantula; the owls lived in the Owlery, but the other pets usually remained in the dormitories and common rooms; however, Ron often carried Scabbers around, and Neville took his toad Trevor with him to classes, as Professor Flitwick made Trevor zoom around the room in Charms, and Snape fed Trevor a Shrinking Potion (SS5, 6, 7, 10, 16; PA5, 7; GF20)
