Erect Tail

Erect tale is a common pre-sign stage,
but is hard to catch on tape
mostly because it is an early stage, not accompanied
by vocalizing just yet, so I can't hear-and-follow.
I have to see it and have the camera ready and near.

Should I Groom or Attack

A Feline Hyperesthesia Syndrome episode
has very distinct identifiable stages
indicating the increase in severity level.
Judging ongoing severity is important because:
1. Episodes vary in length, Longer episodes
might evolve slower.
2. Episodes can terminate at any stage without fully
evolving, with or without the aid of Valium.
It is important for the immediate judgment call regarding the
next dose of Valium.
The grooming stage, comes as the last non-aggressive stage.
During the tail-jumping stage, she hardly grooms, if at all.
This video shows the transition period between the stages.
She has a dilemma which seems almost funny:
Do I like myself and groom, or do I hate myself and attack.
She tries both in turn, and misses on both counts.
