Cats - Every color
Dogs - Every breed
Fire Crabs - The fire crab looks like a tortoise with a jewelled shell which can shoot fire out of its rear end. It is constantly in danger of being killed for its shell, which unscrupulous wizards will use as cauldrons.
Mice
Puffskeins - A long-tongued custard-coloured little furball that makes a calming purring noise. These pleasant creatures are often kept as pets, particularly by wizarding children. As scavengers that will eat anything from leftovers to spiders, they are very easy to care for.
Rabbits - These particular rabbits change into a top hat and back.
Rats
Ravens
Streeler - Giant African snail that changes colour every hour, and deposits a trail of venom as it moves that kills and shrivels all vegetation over which it passes, and which can kill horklumps. It is often kept as a pet (FB).
