Among those who noticed the commotion at the door was Halil Akyürek, an emergency room doctor who works at the hospital. He ran in to help.
"The cat's neck was totally stuck," Akyürek told news outlet Haber Turk. "He was struggling and having trouble breathing. I put my hand on the back of his head and properly removed him from the door. We immediately began CPR."
Dramatic video shows Akyürek massaging the cat's heart, coaxing him back to life.
