I went to my local Tractor Supply to get some. Luckily I was able to get four boxes of Durvet brand — not sure if these stores are still selling them.

So I decided to read the small print on the side and back of the box. One of the last statements on the back caught my attention:

WARNING: Do not use in horses intended for human consumption.

Do people actually raise and butcher horses like they do cattle? (It's supposed to be illegal in the United States.)

Seriously?

Yuck!
