Even though I’d set up the cat tree on her insistence, Donut jumped straight onto my neck and settled in.

“Goodnight, Carl,” she said.

“Goodnight, Donut,” I said, patting her head.

“Promise me you won’t let me die alone like GumGum’s mom,” she said. “Or GumGum. I guess she died alone, too. She was probably really scared.”

“Don’t worry, Donut,” I said. “We’ll find out who’s responsible, and we’ll make them pay.”

I'm just reading the "Dungeon Crawler Carl" series (which includes "The Dungeon Anarchist's Cookbook") and he sort of inherits his ex-girlfriends cat Donut. Then the earth is flattened by aliens because we failed to file and appeal 50 years after first content and Carl is forced into a Running Man style dungeon for the alien's entertainment. Luckily his cat Donut evolves and becomes intelligent and can shoot magic missiles out of her eyes. She later says:

“You promised me that I wouldn’t die alone,” she said. “You can’t keep that promise if you die before me. We do this together.”
