I have this condition

When I am very very very happy . . . like when it's first thing in the morning, Dad's having breakfast and he holds me and I'm in the way of the cereal bowl and the hot tea--I just start purring. I can't help myself. I purr really really loud so even Mom, who's playing the radio too loud in the car for YEARS can hear me.

But then the condition kicks in.
I start hacking and coughing.

Dad calls it happy asthma.

Everyone should feel so very happy that they purr too loud and cough.
