🐱 Cosy Kitten Home: Eight-Activity Care Sim with Day Clock, Coins and Levels

Raise a playful 3D kitten in a sunny living room: five live needs (happiness, hunger, energy, health, cleanliness), a day-night clock, daily tasks, coins, levels, feather-wand pounces, yarn rolling with friction, brushing, napping, decorating, friends, outings and photos. Real kitten energy maths (RER = 70 M^0.75), ballistics and rolling friction, with in-page numerical checks.
