Sure, I'm skeptical of the claim.

But your attempts to equate it to the human experience are a waste of time. Nobody actually thinks humans (or cats, or bison) face the experience that SoftTalker was trying to describe. When we go by the actual intent of the statement, either it's true and mice but not humans face that, or it's false and neither mice nor humans face that. Any experience that you can say is the human default in full honesty, is not the experience SoftTalker was trying to convey.
