Does anyone on the board have any of these? I've been thinking of getting 1 of the two and wondered if anyone can answer the last question I have. I've been able to find out most needed information about feeding, enclosures and health. The last question I have is how many times a year the actually enclosure needs to be completely changed? The only thing i've seen is 1 site mentioning roughly 3 times a year but was never able to confirm this with another and it does seem like along time to wait.
