NAW-Tee Kat!!

How's about...

A Bigger Bell?

One of those "Key Finders" on her collar?
They are a two-piece "system" - the *Beeper* recieves a
signal from the Transmitter and *BEEPS* to enable you to find your
misplaced key ring. Substitute KAT collar for key ring.

And now they make lil Blinking Lights to hang on
pet collars - motion activated.

Sorry bout the No-Sleep problem;
but GLAD she was found in somewhat short order!
