OHHHHHHHH. Ok now I'm much less concerned but it still puzzles me.. My snakes urate probably.. oh.. once a week but they are ball pythons. I can't imagine that red tails and ball pythons differ to much from each other in the matter of defecation. This is going to sound strange but do could you give a description of the urates? is there anything strange about them? quite frankly it sounds (to me) that your snake may have been a bit dehydrated before now? maybe the humidity/ weather of spring is getting to it.
