ok i saved a ball python from someone who longer could care for it, was somewhat neglected. seems kinda thin but is active. he had tried shedding but was shedding in pieces, i added the right heat bulb for temp and some humidity well he shed the rest off. but recently ive noticed some scales seem darker and feel kinda sticky on some spots on his back almost look wet. they also appear kinda light red like little sores. I already let him soak but still seems the same. any ideas?
