In most cases the person is unaware of there abillity to shapeshift and during there first shapeshifting experience beleive hat they had blacked out while defending themselves and regained conciouness later. There are no real way to tell a werecat from a normal human other than there pointed ears, and occaionally they may have sharpened small fangs somewhat like a vampire. Once they have learned to control there anillity it has been stated they can turn into normal cats at will, and turn into wild feral cats.
