Ball Python has not digested

[Skiploder]

I last feed him monday i check his tank but none

What is the hot spot temp?
What is the ambient temp?
What is the cool side temp?

By the way, just because you can't see a turd doesn't mean he hasn't digested it.

I would worry less about whether he's digesting his food and instead concentrate on getting your husbandry nailed down.
