Cats have many folkloric associations with ghosts. In the UK, white cats were linked with ghosts, and black cats linked to death. While cats in Japan can be linked to good luck, the bakeneko were cats thought to be possessed by ghosts or demons, who could walk like humans, talk, and shapeshift.

While dogs seem like the better choice to train to follow commands, cats can also be trained. The important thing to know is that they have different motivation levels to dogs and will often consider the cost/benefit trade-off in learning to be much lower.
