That's interesting about catching them in the hide. I noticed the last two feedings she was out roaming and when I presented the rat she seemed interested, but then retreated to the back of the tub. She would do this in the T8, except she would retreat to her hide and then eat the rat at some point during the night.
You haven't had any issues with yours wedging themselves between the top of the hide and the above shelf? What hides do you use?
