Blue Tooth?

The only tooth I know is the one in my mouth and I don't have many of them and from what I can see.. they are white though some are slightly yellowish. I am not a spring chicken so I'm sure you can understand that.. hehe..

So imagine my surprise when mommy told daddy that she needed a bluetooth something.. I think it was a Bluetooth headset or something like that.. what kind of tooth is blue and requires headset? Is there a talking blue tooth out there. I guess though I am a "woman" cat, I still have so much to learn about the human world...Sigh!

Cheerio...
