Death: The Feline

In the bustling city that some of my family and I live in, there is a feline that follows people around on their last day on this death forsaken planet, and no one understands what the cat actually looks like, since the only people that see it are going to perish. Everyone thinks it's a black cat, since they're 'unlucky', but I believe that this cat could be a fluffy tabby cat that looks completely harmless.
Either way, I'm not dying any time soon, so I'm just going to focus on the now.
