How to set polymorph variant?

[Puri]

Ok, perhaps dumb question, but how do I set the Polymorph variant for poly in a macro?
They are all called "Polymorph" in the spellbook, and "/cast Polymorph(Cat)" for example does not work anymore.

Just to update, it's the crittermorph glyph. Everything works fine without it.

I've had Crittermorph since 7.0, my variant macro still works fine? Probably because it's (Black Cat)?

Wanted to share a macro I use to give you an idea:

/clearfocus [mod:shift][@focus,dead][@focus,noexists]
/focus [@focus,noexists]
/castrandom [@focus, harm][] Polymorph(Rabbit), Polymorph(Turtle), Polymorph(Pig), Polymorph, Polymorph(Black Cat)
