Its perfectly natural for live animals to be eaten by predators. Should we go through frozen euthanized rabbits out in the woods for the mountain lions? I don't know if I could watch it, but I don't think its such a bad thing.
Have you ever been tried to breath where there is no oxygen? Its awful, How can you say that that is humane? I personally wouldn't trust a pet store when they say they are humanely euthanised, and for what reason would a frozen mouse be healthier than a live mouse?
:lol:where do people get this idea that its cool to have a killer fish? it's STUPID... you want vicious? get a cat. drop any mouse in front of it and watch what happens
