I know it's part of the 'moefication' but seeing the title be 'breast tumors' is such a cognitive dissonance-gut punch, good thing the owners care b/c i can imagine there being parents out there that 'cave in' to giving their kid a pet but not bothering to do vet checkups let alone treatments (although these days there are some ppl asking for small donations here and there for vet bills but idk how much that helps unless you're already notable online or get boosted by some kinda pet help service)
Hm, wonder if some kinda spinoff game would be made, i vaguely remember there being an osmosis jones one (looking it up there is one, not the cat specific one but just overall lol which i guess isn't surprising given the success of the 'main' story and all the spinoffs)
