Ridley, if he can't keep up with the work of keeping them in clean and decent conditions, then he shouldn't have them, period. Same goes for pet hoarders and puppymills.
Can't handle the care? Don't keep so many. It's not hard.
I'm not talking about a snake that defecated the same day or tipped a water bowl and just hasn't been cleaned yet....we all have those. I'm talking about the dried on feces, the yellowed newspaper, etc. Nobody should ever be "too busy" to take care of that.
