I would very much recommend NOT getting a cat, especially not a black one. Black cats are generally the worst of a bad species, and they're often familiars of witches or warlocks. Sometimes they're actually warlocks assuming that shape in order to remain incognito. Please, do NOT get a black cat.

I would also recommend getting a dog. Any kind of dog is fine, as dogs are the best possible pet anyone could ever possibly have. Dogs are smarter than any other pet, have more personality than any other pet, and generally, they demonstrate a higher moral fiber than any other pet. Dogs are like the angels of the animal kingdom, and they WILL protect you from evil spirits and so on.
