The farm bill makes 'hemp' anything with below 0.3% THC legal. For this reason, we have a LOT of testing on the THC content of cannabis, since it is required to sell and manufacture. As it turns out, naturally cannabis quite commonly has >0.3% THC even before heating or activation of THCa.

Any human-like animal with our receptors eating a large amount would get high as fuck, cooked or not. A ruminant eating pounds of the stuff raw, would not be that different from a human consuming an ounce of baked pot.
