"Sarah," Kiki purred in a sing-song tone, "on the grass like a good girl..."
Jon and Karyn gaped.
They began to run in the other direction, very freaked out. Karyn suddenly noticed Jon wasn't next to her and turned.
Jon was standing, frozen, by a grey and black striped kitten.
As Karyn watched, Jon fell to his knees. His hands changed, fingers becoming stunted and stubby. "Jon!!" Karyn screamed in horror as Jon shrank, eyes becoming wide with fear as they began losing the intelligence behind them.
Jon's brow retreated, the brain inside shrinking with it. His clothes fell to the ground, but he was starting to grow a pelt to cover his nakednes. Before long, a short, hairy, ape like being that somewhat resembled Jon turned tail and headed back into the house, dragging its knuckles along the ground.
Meanwhile, the grey and black striped cat walked on all fours into the pile of Jon's clothes and stood up, his spine straightening and reforming. His body began to grow in size, his legs growing longer until the front paws split into individual clawed fingers. The area above his eyes thickened, cranial development increasing to accomodate a significantly enlarged brain.
Karyn panicked even more, and continued running.
