It was bound to happen. We started to let the cats up from the basement a few months ago. They adore going upstairs. However, one seems to have found the worlds most expensive cat toy, and has hidden it from me.... can you guess what it is?????????? (hint, not the pump, its always attached) if you guessed the minimed CGM shell.... BINGO-your spot on. I had it on the desk to re-charge and see if I could pin matt down and put it on him. I think he bribed a cat into taking it. Its gone, I cant find it anywhere... and nobody is meowing. I have offered up a catnip ball in its return, they must really like that shell. I should have known the way they play with those caps that come off the sets... we have hundreds of them on the floor.
