And regarding her aversion to touch.

I have had, over the course of my 42 years, about a dozen cats. On and off. So it is a fair size sample that I have observed.

My observation: cats differ WIDELY in their attitude towards touch.

And, supposedly, humans are more complex than cats.

In the cats that I have been exposed to, aversion to touch has correlated with having had a difficult past.

Maybe the same in humans... do not know.
