I don't even know who this person is. I'm not a follower of instagram and have not seen these pictures myself nor do I wish to. I've always believed that a person should feed their animals whatever gets them eating and keeps them healthy and their natural prey is quite often the best for them. But I not a fan of posting feeding pictures or videos no matter what the animal is being fed whether it's mice, rats, snakes, lizards gerbils or whatever. Yes, you could argue that some of these are educational and instructive but the overwhelming majority of feeding videos that I've seen posted on youtube or elsewhere were solely for the enjoyment of watching an animal die. These are the kinds of videos posted by people who think that C0ck fights are a lot of fun and dog fighting is a wonderful sport. In short, the types of people who should not be keeping animals of any kind.
I'm not claiming that the person posting these videos has sunk to that sort of depravity, if he's not feeding a live piebald (as was implied in the first post) to his cobra but is instead putting an already dead animal to a use other than throwing it out and wasting it, then I see nothing wrong with that. But WHY POST A VIDEO OF IT?
