As far as I can tell, the Pet Chime is designed for those who never want a moment of peace ever again. Dogs just can’t reach the doorbell, or maybe they just can’t grasp the concept of a button that opens the door, being attached to the door.
Apparently, the Pet Chime can be used inside or outside, so that your pets can inform their owners when they would like to be inside or out. As every pet owner knows, that would be every five minutes…for the rest of your life. The “paw” doorbell component operates on a 9-Volt battery, the ringer operates on three AA batteries. It will only cost you $25-$30 USD to never again be able to relax.
