When my Lilith was sick she would gag. I was told the reason a cat gags is because they are trying to get more air. In other words they are having difficulty breathing. I would take her in just to be on the safe side. It's best to catch any type of problem early. JMO. Keep us posted ok. Millie has always been a favorite of mine ever since I first seen her in her marvelous 'millie in the sink' photo. But then again I am partial to calicos too.
