Hi,
That's because these are living animals not mathematical equations.
There are nearly always a range of answers and possibilities rather than just one.
Trying to work out which one is relevant to the problem at hand is usually a fairly involved process of ruling things out by asking more questions. If we just stuck to offering one solution to each concern then we might never ask the question that suggests it is, in fact, caused by something the OP thought was inconsequential and so never bothered to tell us until asked.
I'm sorry you have such a problem with EXPERTS and know what works for your snakes in situations where you can actually see the animals and know every possible variable in their care and behaviour.
