It's hard to know if the cat does understand, though Shepard feels safe going with the theory that he isn't just a regular old cat. No regular olds here. Even a smart cat will do, she thinks as she strains not to panic at her situation. A smart cat could bring someone else. If there is anyone else.

"You want me to - flip?" The fact that it wants something and can express as much bodes well. With a small grunt, Shepard follows instructions, rolling onto her stomach. Maybe he plans to walk on her back. She'll take even a cat's plan right now.
