Animals have visible eating animation

In 1.14 you added foxes, foxes can hold items in mouth, pounce have a sleeping animation and progressively eat edible foods inside their mouths, well why doesn't all animals have this? Personally i believe this would be a great idea. Especially going towards tamable pets, at night time the animals will find a dark place to use their sleeping animation and then in morning they'll search for food eat with eating animation and repeat, they will also use hunting animations for wild ocelots and wolves (stalking and pouncing) this will definitely make the game more lively and full of action animal lovers will definitely love this update.
