the pic below shows the opening in the back of the rock, so u can see how he'd feel in secure,--- his tank has been some what re-arranged since this pic




and here's a couple quick cell phone pics showing what I did to the left hide, he just ate 2 mice and is under the right side hide now,(so no pics) but I basically cut a arch shaped piece of cardboard with flat bottom and illuminated 25% (everything from the right side of the entrance over) of the space in the hide with the new "wall" - there are more pictures in the "pictures" forum currently on page 3. --- also the marker I used was a crayola, washable one, no scent at all.
