I used to own a snake, absolutely loved her. But I couldn't stand feeding time, quite simply because of the process. In fact, my ex tried to feed her a rat, but I saved it and made a great pet out of him too! But, we all have to make choices.
Honestly, what kills me is, like I said, people who raise rabbits for lab use. I can't imagine the torture they must go through just to make sure things are safe for human use.
