I have one analog just to the left of the hide about 1" from the substrate and about three inches from the hide, one digital about five inches from the hide and about 1/4" above the substrate and another analog on the opposite side about 1" above the substrate. The digital is usually only about two or three degrees different from the analog ones. The hide is one of the brick red terra cotta rock-like hides I bought from petsmart. The mouse was live but only because I just got it and the woman I bought it from (Silke @ wildthings in oakwood) was feeding it live and I thought I would just feed it the first one live so that it wouldn't be too different but switch to f/t when it got used to the cage setup. The feeding went fine I watched the whole thing the mouse sat in the cage for about ten minutes then the snake saw it from its hide lunged out of the hide grabbed it and wrapped it up and swallowed it no problem.
