I learned a new word yesterday (or more correctly a new expression) to describe something I have seen most days for several decades.
The word in question is Lordosis (or more correctly Lordosis behaviour)is describes the presentation response of female cats in oestrus. Also tickle a cat at the base of its tail and it raises its bottom or at least mine do
And that is Lordosis behaviour. 24 hours ago I didn't know that...
Sorry, I'll do a better post later!
