TLC for old mobs. (Animations and models)

Old Generation minecraft mobs should be updated to reflect the current standard of mobs.

To explain, the animations and models of minecrafts legacy mobs (in specificacy, mobs such as cows, pigs, chickens, sheep, wolves and other legacy mobs) do not match the quality of current generation mobs (foxes, cats, wardens, dolphins, etc) The fox, for example, has sleeping animations, and a jump animation, cats will come to lay on your chest, the camel will lay down to rest, small animations such as these breathe life into these mobs, life that is lacking in our oldest world companions. As such, I believe that our old friends should receive a little tender love and care, and be updated to match the rest of the mobs in the world.

It doesn't need to be much, but little things like chickens pecking the ground, or pigs occasionally rolling to take a dust bath would bring a lot more life to our worlds and farms.
