I'm glad to say, no, I have never. It's something that I just can't make myself do. Although, I'm guilty to confess that I can't say the same for reptiles i.e Komodo Dragon. I cannot forgot that one incident I read on newpapers...... this 9 year old got killed by a Komodo dragon in Indonesia. I can imagine that.....especially after witnessing the feeding time of these predators.
