You see a figure approaching your house

The figure seems to have cat like features even thought it’s standing up like a human being with a pretty good posture

Maybe it’s a costume?

The figure gets closer to your house while bouncing a little bit and you now see a pumpkin shaped bucket dangling around in their left hand

They’re at your door and knock

You open the door to see a humanoid calico tabby cat looking at you with big shiny eyes and a big smile

In an exited voice they say “Trick or treat!”
