My kitten scared this shit outta me...

He did it last night and this morning. Waking me up terrified. When he is coughing up a furball he screams. And when he screams it sounds terrible. I leaped outta bed bc I thought something horrible happened to him. He sounded like someone squished the breath out of him. When I realized he was okay, I finally fell back to sleep. But when I woke up he scared the shit outta me again.
