interactive npcs including babies, realistic pets and hiring npc workers

examples
npc babies: adoption center sound the most reasonable way to get them thise includes a contract for care and fees for neglect or even cps if thats not too much hehe.
realistic pets: a pet sanctuary that hold pets no rarity involved just pets and species within like dog breeds, cat breeds, reptiles and birds also fees for neglect no trading but rehoming could be a nice concept
npc workers: (gardener, chef, butler, personal driver..etc) npc worker should cost money but reasonable dependig on their job.
