"calm down, Is there something I can do?", she thought. Suddenly, whe spot her own clothes on the floor. She thought it would be work, at least partially, even she wears them on while she is still stuck as a cat by the collar. Anyway the ring is still on her, isn't it?
She crawled into her shirt laying on the floor. But, eventually, inside her shirt, she passed herself through the right side arm hole rather than the neck one at the center. She noticed it when only her hind legs end tails still inside her clothes.
... it worked anyway,
The part of her cat body inside her shirt started to expanding, forming her prior human body to fill in the shirt. Meanwhile, being surprised, Jessie was watching it, her human body returning under her cat body. More surprising thing to be happened, her human head formed on her torso, while she was having a cat head on where right hand to be.
Finishing the change, Jessie noticed her human sight turned back. It was quite confusing to have normal sight of a human and another shight of a cat from the second head at the tip of her arm. "It worked partially... aww, this is bit dizzy..." she said, from her human mouth simultaneously with meowing from her cat one. "Can I make this thing normal?"
"... And how can I stop meowing every time I say something?"
