Lone Wolf Development Forums - Question regarding shapechange as a racial ability

I'm trying to create a race with a specific shapeshift ability

I am trying to create a race that has the ability to shapechange into an ordinary housecat using the shapechange as beast shape III. I know how to bootstrap the shapechange to the race, but the problem is I want to limit it exclusively to a cat (and maybe other similar creatures such as tressym).

I have raChangeSh bootstrapped with
FIELDS
livename : Beast Shape
sbName : Beast Shape
TAGS
PolyEffect : BeastShap5

When I do this the desired selection of "Cat" does not even show up on the list of acceptable forms for the polymorph. I dont know why since a cat is an acceptable selection for Beast Shape III.

I know where the race selection list is found, as I have looked it up on the cloak of the bat, but trying to add this is proving troublesome. As I dont know the PolymoHelp is to create a script for it when attaching it to a race.

From the Cloak of the Bat

Code:

gizmo.child[PolymoHelp].field[foCandExpr].text = "Race.rmBat"

I am fairly certain there are a few races that do this, but off the top of my head I can only think of the kitsune, which doesnt really work since thats really not what I am looking for.
