A couple days ago I had to go to the hospital due to severe chest pain. (Nothing to worry about. The problem isn't my heart but one of my nephews who likes to lie on his uncle like the latter is a recliner. ;) My sternum and ribs apparently can't take the weight of his head.) Anyway, in my moment of intense pain at home, I had a couple of symptoms happen all at once, especially nausea and cottonmouth.
So Milady and I went to a nearby hospital where a doctor and two interns decided to examine me. The doctor asked for my symptoms, and I mentioned the cottonmouth.
She looked very surprised. "Cat-in-mouth???"
One of the interns corrected her. "No, cottonmouth."
"Cottonmouth???" As if she had never heard of the condition before.
"Dry mouth," I said, hoping that she finally understood me.
Some time later the thought occurred to me that "cat-in-mouth" is probably just as appropriate to describe the symptom as "cottonmouth." ;)
