I own snakes & love them. I don't own them because it's cool to watch them eat. I own them because I think they are beautiful and amazing animals.
That being said, I do feel bad for every animal I have to offer as a prey item, which is part of the reason I make sure the rodents get the best care/food and love possible. Why not let them have a great life until the end? The rodents in my care are probably taken care of better than most pets.
I personally cant stand watching videos of people laughing when their reptile strikes/kills another animal. Which is why I chose not to watch those videos. If someone doesnt like what they are seeing, there's always the "back" button.
I think people who can laugh at any animals death is warped in the brain. Yes it has to happen but there's no need to laugh about it.
No offense to anyone.. it's JMHO
