Cattle look like they can be sweet, but I don't think they have a lot of brains in there
I resent that statement. I grew up on a dairy farm, and have spent a lot of time around cattle. I've come to respect them, as people respect horses.
We rent land off of a couple, and they have an unaltered bull. He is the sweetest thing. Whenever I need to go into the pen to get water, he comes up to me and demands a head scratch. The owners can't bring themselves to slaughter him, because he's just too friendly.
However, getting into a pen with a breeder bull is kind of stupid.
