Welcome to the Slaughter House! I built this cow farm while trying to figure out how to make a large cow farm in creative to put in a survival world, but then it just kept going and I just finihsed it. And I really am satisfied with how it turned out, I spent longer than I'd like to admit on it...

I had a red stone circuit to kill the cows, but they would always swim up the lava, so I gave up and just put a lever on a dispenser. So you have you click it four times to get the pulse, but at least there is control :D

Steelfeathers's Dandelion Resource Pack is my favorite so I use it all the time, these screenshots are no exception ^^
