We used to have this huge red bull (he was actually 1/4 buffalo) and he was really smart. When you wanted him to get in the trailer, all you'd have to say is, "Walk in the trailer, Big Boy" and he'd walk in there and just stand there until you closed the door. The only way he'd get out of the trailer is if you said, "Get out of the trailer, Big Boy." He was so smart. He was old though (10 years when we got him) so we didn't keep him too long.
Then there's the show heifers. Some of them will see their rope halters and run up and stick their heads in them. Others will flee at the sight of their halter.
I had one simme heifer get out of her pen one night (a few nights before Christmas) and walk down the gravel road. Someone went to my neighbors house and said there was a car chasing a "big baldy steer" down the road. He went down and looked at the "steer" and it wasn't his so went to our house and told us about it. We went down there and it was my show heifer. He asked if we needed any help chasing her back in the pen so I told him no because I could just put her halter on her and lead her back. He just laughed and said "yeah right." So I went down the hill, put her halter on her and lead her back into her pen easily and he said, "I never saw anything like that before in my life"
One of my previous show heifers "talks" to me. I'll walk out my front door, she watches me. I'll say something to her and she'll bawl in reply to everything I say. She's spoiled though. I always pick grass for my show heifers and they eat it from my hands.
Cattle have feelings. They're also smart. ;D Well, most of them are smart - there are some that aren't.
