This is my interpretation of the Heavyside Layer.

If Old Deuteronomy chooses a cat to go the Heavyside Layer, that cat is reborn. If a cat dies, they are sent to the Heavyside Layer and stay there.

I don't own anything.

"Great Heavyside, is he alive?"

"I don't know, he's not moving!"

"Is he dead?"

Alonzo grumbled. "Five more minutes," he mumbled, turning on his side, attempting to drown out the voices.

"ALOOOOOOOONZOOOOOOOOO! I'M SOOOORYYYYYYYYY!"

The loud and sudden apology caused Alonzo to bolt upright. "Wha-whuh-huh?" he spluttered, looking around. He was in front of the Jellicle Junkyard, and in front of him was Pouncival, Plato, Tumblebrutus, and Admetus. Pouncival was sobbing into Plato's shoulder while Tumblebrutus and Admetus attempted to comfort him.

"Guys, what happened?" asked Alonzo, but they ignored him, as if he wasn't even there. Alonzo tried to remember. They were playing tag in front of the Junkyard and Plato tried to tag Pouncival, but a car came out of nowhere and...

Alonzo's eyes widened.

The car missed Plato and hit Alonzo.

"Hello Alonzo," a voice behind him whispered. Alonzo turned around to face a dark gray queen, and a beige tabby tom. Alonzo gulped and answered.

"Hello Mom, Dad."

Alonzo's parents, Sasarada and Orion, had both died when he was still a kit. Alonzo was watching one of Mistoffelees's magic shows when he had heard from Jellylorum that his owner's house had burned down, and his parents were both in the house at the time.

"ALONZO!" screamed a female voice behind him and Alonzo turned around. A mass of white and dark brown fur collided with him, knocking him off his feet.
The cat that had just jumped on the black and white tom bounced off, and Alonzo recognized the brown-faced white queen. It was his sister, Silhouette, who was murdered by a Pollicle around 4 years ago.

"Well, well, well, look who just joined the party," murmured a voice from behind Alonzo, and he turned to see his black and white patched brother, Tavarius, who drowned last year.

"What are you all doing here?" Alonzo asked, smiling. Sasarada smiled a sad smile and pointed behind Alonzo. Alonzo turned to see his body, limp on the ground and stained with red.

"So, I'm dead, right?" he asked, looking back up at his family.

Silhouette shook her head. "Not yet," she replied. "You're still alive, but barely. That car that hit you caused some major damage."

"Then what are my chances for survival?" Alonzo asked again.

Orion replied, "That, my son, is up to you."
