I am almost certain that she can get in through a 4 inch opening.
A piece of 4 inch PVC can be used to line the hole you cut in the cooler.
My suggestion is to use cooler upright. Easy to open lid to install carpet/rug/pad/etc.
Place the opening at bottom and end of the longest dimension - gives a sleeping area farthest from opening.
Try to orient the opening away from the prevailing wind.
A piece of carpet on the bottom would be nice for traction.
I suggest a padded ELEVATED sleeping/resting area at the end farthest from the opening.
Not a fan of heating pad in such a small enclosed volume.
I have no experience in this matter - just hoping common sense helps.
