Really? I read no aggressiveness in that, but just a very plain statement. Remember, its not always easy to tell the tone of the written word.
I do not condone the feeding of stunned rats, it's extremely painful for the animal, and much like the dog in pain that bites it's master, if the prey were to wake up, it will be extremely confused and incredibly defensive, it could do some real damage in a short amount of time. Plainly just not humane for either animal
Feeding live, the animal is unaware of the risk of danger and mostly non chalant (from what I've seen most often).
Feeding prekill, FT, or even live is best for both animals imo.
