Clearly, the Bible - by using this kind of terminology - shows beyond any reasonable doubt that the basic nature of cats, while created perfect by God, has become evil or 'beastlike' since the fall of Adam six thousand years ago, and more probably, since the Great Flood of Noah's time (c2350 B.C.E.). This is a development of the condition borne by the 'Original Serpent', the 'Great Dragon' Lucifer himself. (Gen. 3:1) Indeed, modern studies of classification of cats, while not necessarily being reliable as they may be based on the discredited 'theory' of evolution, strongly associate felines with serpents (despite some external differences in physiology and morphology, which confuse those who do not study these matters deeply).
