David: after giggling for 10 minutes at the mental sight of you and your cat
eating corn on the cob  together, I still must ask:What is un-instinctual
about your tale? How do cats come to delight in other specie milk, since
they were domesticated fairly recently, unless this is an instinctual need
for the other species fats they evolved eating? How do birds come to seek
milk at ALL, unless there is an instinctual need for any fat at all (both
carnivores and scavenging crows, ravens, vultures, no matter the species,
developed this need via evolution)?
