Whew, finally some plot development. Guess I'll keep following for now.

That thought has crossed my mind, but I dismissed it because the way Zen's lines have been phrased felt like the cats had died on their own (probably from his mother's spirit negatively affecting them). And it didn't look like their spirits reacted to Satoru at all, which would have been a major tell. Then again, it would make sense if he was revealed to be the one to sell out Zen's first cat to his mother, but then it calls into question why the dead cats aren't haunting
him instead. For the sake of consistency I'd rather he wasn't the culprit. Besides, that'd make Zen even more miserable: being asocial due to mommy issues is one thing, but also having his only friend be an animal abuser veterinarian is literally laying it on too thick.

Actually this
was a gag trope manga until, like, a few chapters ago, lol. And this is the climax of its first actual attempt at a story arc. It didn't have any story prior to that—just a premise and a series of mostly-interchangeable vignettes based on it.

Yeah, that's... not exactly a surprising metaphor. She looks like a spider because she was a control freak and sucked the life out of her son while she was alive. Pretty much what a spider does to its prey.
