I know most of the few that do keep this species are able to keep them outdoors year round. I have a group of 5 yr old Mee's. Mine are kept outdoors from late Spring to early Fall, and indoors throughout the cold months. What intrigues me by observing this group over the past few years is the way they react to the two environments. It's opposite how I would imagine it. Outdoors, there is not much activity at all. They may go 2 straight days, once in awhile 3, without moving from their hunkered down spot under the vegetation. What's stranger is seldom do they hang out for any length of time in their watering holes. They eat and graze, but growth during these outdoor months is minimal, if at all. Now, INDOORS is completely opposite. Within 2 weeks of coming indoors for the Winter there are noticeable growth lines on all of them. They must eat daily, or they go nuts. In fact anytime I enter the room they immediately come charging and climbing the walls to get at me for some food, even if they ate a few hours ago. Also, they will spend most of their day hanging out in the watering holes enjoying their day. It's almost as if they prefer to be indoors vs outdoors, which is a ridiculous statement. They act and grow like I described indoors ALL through the Winter. The first couple years I just kind of chalked it up as that their natural instinct to fear predators at this young age was keeping them so reserved outdoors. But when they are active outdoors, they have no fear of anything. Strange. I've never experienced anything like this to this extreme with any other tortoise species I've kept.
