Cougar In Training 

A woman in her thirties sharpenings her skills for when she becomes a Cougar sometime in her forties.
CITs can be found at bars, clubs, social gatherings, or anywhere young male meat may congregate.
They may roam alone or in packs at any given hour.
Their levels of sleaze and devil may care attitude are not fully developed and therefore lack the natural instinct that overflows in their competitors, the cougars.

Misty, a cougar in training, surveyed the bar for her next prey. Even though there were other CITs prowling around, it was the cougars she had to watch out for.

When you are in your late 20s about to hit 30 you are considered a baby cougar in training. Meaning that from age 30-32 you have a leeway period that allows you to transition into your new role as a cougar.

Damn your about to be 30 and a baby cougar in training. It’s all good though you have a 2 year leeway period until your 32
