I told Phil and Brent that I needed someway of knowing if Orion was inside or outside. She likes to hunt under the deck, she can't hear me when I call, and sometimes I just forget I let her out. My concept was a block of wood w/ "IN" and "OUT" scratched in it. Two holes - one under the "IN" and one under the "OUT". A peg for the hole indicating the status of the whereabouts of the cat and some yarn to keep the peg from being lost. Their idea was this picture - silhouettes of cats to indicate "IN" and "OUT". The holes and peg became magnets. The yarn became an elegant leather strap wound at either end w/ silver wire. The base is oak and the cats are in walnut. Very cool. Indy wanted to know where her "indicator" was. I explained it took a long time to train her and she was too valuable to just let outside w/o monitoring so, for that reason, she didn't require an indicator. She was quite gratified w/ that answer (and the treat that accompanied it). I explained the indicator to Ori. She was summarily unimpressed. In her estimation, if I just stood ready to let her out and wait until she wanted to come back in, no indicator was necessary. She did think it was pretty though.
