We actually got the magazine article.... and it comes in "kit" form (no
pun intended) ...

You get:
Temperature
Pressure
Frequency of movement
Ambient light.

In this article, the guy put a receiver next to the cat bowls, so he
could even tell when his cat went to "nibble". They have a cool graph
created from the data that shows when the cat went outside, went to his
bowl... etc.

Apparently the "pressure indicator" shows how high the cat jumped...
e.g. been climbing a tree, or just having a snooze at ground level....

I think there was a link to the magazine article there too. Just
thought the gizmo might be handy...  And yes, you are absolutely
right.. no price was mentioned... :)
