Well, I put some food in the Mondale's new feeding tank. Mondale seemed to regard this as bait and was quite disturbed. He did check things out though:
As soon as the flash went off, he was spooked and ran away. Isis, however, was curious. He can't even get his head in there. He also tried a paw, but it didn't do him any good.
Apparently, Isis decided that if you can't actually have the food, you should at least be King of the Food Container.
Once Isis had marked it as the safe zone, Mondale came over and had a snack. Why on earth the little cat thought that it was best to actually climb in there under the twenty-five cat, I'll never understand.
Mondale finished his snack or got paranoid or was distracted by dust, it's hard to say. Anyway, he left the contraption and I managed to get photgraphic proof that he fits through the doorway. I might make it an inch or two taller tomorrow.
