GEN661 Out of His abounding goodness to mankind, God put the fear of man into dangerous wild creatures so that an infant be safe from cats, rats, and the like.  When a man dies, however, he is no longer safe from them, as our Masters, of blessed memory, expounded; “A day-old infant, alive, need not be guarded from rates; Og, King of Bashan, dead, needs to be guarded from rats, as it says “The fear of you, so long as the life force is within you [reading וחתכם as וחיותכם] will be instilled in all the wild beasts of the earth’ (this verse).  Shabbat 151b.  DUTIES 211
