thin (figure, body, etc.)

One week has passed, two weeks have passed. Emily fed Luna generously every day. A normal kitten would have plumped up. But Lunar’s body was almost the same as when we took him in. She was so thin that her bones were visible. When we picked her up, she was surprisingly light, her ribs clearly touching. Driven by anxiety, Emily decided to make an appointment at the veterinary clinic. But this decision would lead her to an unimaginable truth.
