"Well, if you don't already know the answer...it'll clear itself up soon enough."
He finally stops shrinking a little under five feet (including the ears), and his hair, which now seems very well-groomed with a silky sheen, stops abruptly at hip-height. Nate can feel his hips expanding back out slightly while his underwear rapidly shrinks, and then his pants audibly tear at the thighs, the lower parts tightening and softening into a pair of pink-and-purple striped leggings while the rest spreads out into a sky-blue pleated skirt and a frilly underskirt beneath that.
A gentle tug between his legs and then another pull from the underwear up against an unfamiliar flatness is all the notice Nate gets of a sudden change of pronoun, and then, just as quickly as the ears, a slim, blonde-furred tail shoots out from the base of her spine. Her voice stops off at a squeaky high tone as her shirt changes into a kind of dressy white vest, a blue mini-cape-thing held on to her neck by a bright blue ribbon, and a yellow tie. Finally, her chest pushes out all at once into a bra that certainly wasn't there before, growing into a sizable pair of breasts.
'Nate' the catgirl will find she's gained some other accessories somewhere along the way: Little white gloves, a gold-ring-based decoration near the end of her tail, a checkered-pink ribbon on her head. She may find herself acting a bit more energetic and excitable than before.
Seeing the end of the change, Whatevr rubs her hands. "Finally, now I can do
this." And then barks loudly, in a very good imitation of an ordinary wolf.
((I tend to like slow changes, so I hope I didn't go too slowly for you here. Ignore the picture's watch and books and whatever those necklace-things on the blue ribbon are supposed to be.))
