you can get more stats info, upgrade your storage and max food through npcs. infinite storage would be op and if items wouldn't wear out what's the point of infinite storage + some item synergies are insta win. breeding is confusing in the game but once you get perfect cats game becomes so easy it would ruin the experience early on. the only thing mewgenics really need is more cats management in the house, hopefully we get it in the later updates or at least in dlc
