Catapokalips: Black Cat's Survival Story in a Post Apocalyptic World!

All of humanity had perished. Exited. Ended. Extinct.
With the animal kingdom reshuffled, it was up to what was left of Planet Earth's lifeforms to do what was next. This was the beginning of a tale born from the ashes of a dead civilization. When the cinders were alight once more, a new age would certainly come.

Reawakened. Sentience began to spread... like a sickness.
Whether the fire of civilization could sustain it, no one knew, but time would tell.

There was a black housecat who was loved. His name was Zed.
And.
It had been 500 years since the Fall, and Zed had been stubborn in his old ways. Every time he was put at the precipice of despair and on the verge of giving up, he would always find a way to rise once more... just so that he could continue on his stubborn ways... to go roam the world endlessly until he found a human, his next precious human.
So when he found a journal of a dead doctor who had claimed that all of humanity was destined for extinction and that said human was the last of his species, Zed was indignant
The cat could not accept that reality. Surely, out there. a human still lived. But he knew at the back of his mind, it was next to impossible for any human to have survived until now.
It had been 500 years. And. Zed had seen things.
Once more, the cat set to travel... this time to not just continue his search for his next precious person, but also to attempt whether what the dead doctor had claimed to be true.
