Regarding the first animal they don't go on schedule they go when they need to and it depends on a few things, feeding frequency, prey size, whether the animal is growing or not, appropriately fed or not. The only concern should be if there is a bulge that does not go away which is rare.
For the second one you need to feed a bigger prey than rat pinkie, offer food once a week because if you offer too soon after a refusal it will only lead to more refusal. Finally if the animal is not feeding with consistency analyze if whether or not you setup need adjustment.
