Mary decided to sleep on the decision. She had a large dinner, due to the fact that she had barely eaten since the vials arrived. That night she went to bed. Her udder was feeling funny, but she couldn't tell if the sensation was normal or not. She slowly dozed off to sleep and once again dreamt of grazing in a pasture without a care in the world.
Her alarm woke her at 6:30 the next morning. She shut it off and climbed slowly out of bed. Her udder made standing difficult, as she was still a little drowsy, but she managed to get to her feet.
Almost immediately, she could tell something was different. She looked down and saw that her udder was larger than it had been the day before. It was beyond volleyball-sized now, and the teats looked an inch longer as well. Then she felt her tail brushing her legs, but much lower than it was supposed to. Mary saw that her tail was now so long it almost reached her ankles.
"What's going on?" she asked herself, stumbling out of the room. Before, she might have had a chance to hide her udder under a large shirt, but now it looked nearly impossible. The instability the vial box warned her about must mean more than just a reversion to a cow-like form. Cows certainly didn't have such long tails.
She didn't know what to do. She couldn't risk trying a vial, but she couldn't leave the house like this either. Caught between impossible decisions, Mary finally tried to distance her mind from the thought and do something constructive.
As the day passed, she noticed her body changing more and more. Her udder slowly expanded by the hour, every moment becoming heavier and more painful. Her tail reached down to the floor and kept on growing. She noticed fur reappearing on her legs as well, and her toe's nails darkened to solid black. By the end of the day, her udder was the size of a beach ball. She couldn't see her feet beyond its round form. It hung from her body, stretching her skin painfully, its thick veins throbbing. Her tail was dragging on the ground behind her by several feet, and the fur on her legs hadn't stopped growing. It was very thick now, and looked more like a shaggy dog's coat than a cow's hide.
Mary's biggest concern was her udder. She had to do something to relieve the pressure...and she was frightened of what that would take.
