Chirp--Grrr!!!

I was out of town at the WCR State meeting in California when  I    

received the text from my husband.  One of the smoke alarm

batteries had apparently gotten to that critically low level where

it starts to chirp an alert. 

It was 3am (when it started chirping, thank goodness the text came at a more decent hour!).  Cowboy, that handsome cat, decided it was important that he start growling at the chirping smoke alarm. 

I understand neither slept the rest of the night.  Sometimes it pays to be out of town!
