I have some black shale tile in my Rhino cages, indoors and out and for the last few weeks he's been loving it . It gets so hot water will steam on it , YET he loves it . AND no he's not getting burned . he's also shedding better . he will move back and forth from this area that's 130-140+ degrees . he also gets shade or 60 to over 380 MW of uvb (outside) when he wants . BUT most of the time when it 250-380's he's in the shade . When i spray the shale tile with mist , steam will come off of it , both in his indoor and outdoor cages . he not staying there long but , you can tell by how flat he gets , he's like a cold kid by the pool LOL . As noted on KingSnake forum under the basking spot thread . They feel most most of us don't ALLOW them access to enough heat . they can move away if and when THEY desire . BUT they need a cool area also , give THEM the choice . MY Rhino seems to agree !!!
