Do you want to help answer some questions about cows?

I’m in cow country, and it’s made me curious.

1) I saw a cow tied up by her tail. I think that’s cruel, and I’d love to know why anyone would do that.

2) Are there any theories as to why cows have such rough tongues?

3) Would a group of cows be likely to politely wait their turn to be milked? I saw a bunch standing in front of an open door, and it seemed like they were taking turns to go inside.

4) Why would a calf have had a plastic ring put through her nose? It doesn’t appear to hurt, but it seems like there has to be some sort of strange intent.
