Friends? What's that lol. All my friends keep snakes. So, long story short, I trust them all and they are just as concerned about mites as me so I tend to not worry. Only one of my friends have seen any of my animals since I moved last year though. I go to their place more often than not and they have much much larger collections than I, but I'm one of a very small number who even know where most of these snakes are kept. I think it's smart to be concerned about mites just not sure how extreme of measures I would go to.
