Yep, as I said, I really don't doubt any of your methodsI was just thinkin. And it's true that here is actually.. well.. just one breeder right now
And yes, I keep juvenile snakes in plastic tubs too, they often tend to have stress when living in a big terrarium.
And about that illegaly of live-feeding, it's not because they may escape (here is -25 c in winter, they would die), it's because it's wrong for the rodent.
