There is no doubt plenty around that are just learning the nuiances of keeping snakes. As far as years of experience, I was catching, and successfully keeping snakes in the mid '70s. Does it make me an expert? No. Do I have experience? Yes. My exerience has proven a snake doesn't look at a calendar and wait 7 days to eat if it wasn't hungry just 2 days ago. Stress is always the reason a snake won't eat?
I would like to meet the maker of that rule. Thousands of experienced keepers....oh the ones that say I'm brand new in keeping snakes but this is what I think you should do. And those same experienced keepers of snakes that just love to pounce on a newb for using an analog thermometer instead of a digital thermometer made in China. SMH. And what will be the next new rule? I'm not sure, but I'm just glad my snakes don't have internet access to read the rules that have been written for them. Would hate for mine to know they can't eat if there humidity drops to 49% or if it is a mouse instead of a rat. And heaven forbid it has only been 6 days instead of 7 since its last meal.
