Ms. Digicat appears to age one pet year every 24 hours. It seems to be
reasonably easy to keep her in good health, so I'm curious how long
it'll take before she reaches the "senior" stage. And how long a
digicat remains a senior kitty before it "passes on to pet's paradise
in the sky".

The device played a little tune when the digicat moved from the "baby"
to "youngster" stage, and again when it moved to the "adult" stage. I
presume there'll be musical accompaniment announcing her advancement to
the next two stages, as well.

One benefit of the digicat's being an adult is that she doesn't seem to
beep for attention at unexpected times. During the kitten stage (baby
and younster), if there was a digital dropping that needed to be
cleaned up, or if the pet got sick, the keychain would start beeping.
She'd also complain if it was her bedtime and the "light" was still on
in her digital environment. I haven't had that problem occur since I
figured out her bedtime (10 PM -- translating to 10 AM for me since I
have the clock set wrong) and started turning the light off a few
minutes prior to that. (This action produces a little icon of a
darkened light bulb in the upper right hand corner of the screen.)

She's making little digital ZZZs now. Barring any sickness episodes or
"need some droppings cleaned" moments, she'll stay that way until
sometime this evening. Good kitty. :o)
