1)A Kitsune is "Agile(EX)"; +2 on acrobatics checks.
2)A Kitsune can "Change Shape"; an effect equivalent to a polymorph subschool spell (alter self), which changes you into a specific appearance/form.
3)While under the effects of a polymorph spell, you lose all extraordinary and supernatural abilities that depend on your original form.
Question; When a Kitsune is in Human form, (or fox shape if that feat is taken), do they lose their Agile racial trait?
EDIT: What about their "Kitsune Magic(EX/Sp)"?
EDIT2: Bonus Question: Is a Kitsune in human form immune to size-changing and involuntary polymorph spells?
I'd also like to know the answer to these questions :)

Unknown/Dms call. It could be from their body shape, the balance of their tail, or a cultural penchant for kung fu fighting.
As a practical matter, i wouldn't bother recalculating it.
EDIT: What about their "Kitsune Magic(EX/Sp)"?
I'm leaning very heavily towards that one not being form dependent. Magic is more inherent in something being than its shape.

Probably. Keep in mind though that baleful polymorph (and anything based on it) removes all the polymorph effects and then goes to town. After that, a kitsune that knows they're a kitsune can take a standard action to resume their form (as a shapechanger) A kitsune that misses the will save probably doesn't have the knowledge that they can do that.
