CAST Physiology questions.

So I've had this thought bugging me for a long while now (Being the roleplay nut that I am). But aside from sight and sound, Would a CAST retain the other 3 senses they would have prior to becoming who they are now, which of course are Taste, smell and touch-

Would they be able to feel if something's hot, cold, rough or smooth just by touching it? Heck, canonically speaking, do they even need to eat or drink (or at the very least, can do so out of luxury.), or is it a case of Gameplay and Story segregation?

Also do they sleep? That might be another question on my mind.
