It actually is because when you breed you will always have a percentage that will need to be getting started on scented scented (it would be the step before having to assist which is very tricky with a 5 grams animal)
The key is to buy an well established animal sadly many breeders are in a rush to move animals soon as they hatch with hogs I consider my animals truly switched and established once they have ate 10 F/T unscented pink, seems like lot but buying an animal that ate 2 or 3 unscented or 2 or 3 F/T could mean trouble for a new buyer (scenting can be tricky and finding F/T pinkies close to impossible)
That is what I have heard and read, never experienced it for myself.
The worse I have seen it was this

So long it's about 40% you are good, using a substrate that is dry coco coir (like reptile prime) or aspen will help so will having a small water dish (versus big one) and after that it's air flow. I live in the south so humidity during the summer is high and my animal do just fine.
