Cow size

Okay, First off, cows are 1x1x2 blocks(meters) in Minecraft, right? Well, that's not how it is in real life. My dad's a vet(specifically for cows) and he says a mature Holstein dairy cow is approximately 3 meters long by 1.5 meters wide by 1.5 meters tall. My dad also says that this cow deserves a 10x8 meter pen, compared to Minecraft: you can hold 2 cows in a 3x3 area! I just thought that this was something that I should bring to the attention of Mojang and the Minecraft community, so yeah that's pretty much it.
