Samantha sat on her bedroom floor, gripping her leg just below the knee, eyes wide with a mix of fascination and awe. Her bare foot was no longer a foot at all—it was stretching, reshaping, toes melding into padded digits tipped with sharp little claws. Soft brownish red fur sprouted along the top, while the bottom darkened into a leathery black paw pad.

"Whoa…" she breathed, flexing her new toes. They moved so naturally, as if they’d always been hers. She wiggled them, then giggled. "Okay, this is actually kinda cool."
