Last night my cat was outside screeching the way cats do in fights. I ran out to save her. She ran away. Later, she did the same thing. My husband ran out, caught her, and brought her inside. He asked me, "What's wrong with the cat?" Thinking this rhetorical, I went to sleep. He asked again this morning. I jokingly told him, "I'll do some research." Thanks to this image, I found my answer and emailed it to him.
