Very interesting stuff. Kyle, did you order the study? Might explain why Sly did not take to being switched to a bigger, "better", terrarium yesterday. It's the first time in ages that I totally disinfected *everything* and moved him to a new tank. He was doing so much "running around" and rubbing his nose on the glass(totally atypical) that I was worried about him. He eventually settled under his favorite hide and hasn't been out since.
