Moose Foods (or: The Pistachio Boundary)

So far, we have discovered two foods that Moose doesn't like: pistachio nuts and kumquats. I love them both, though there is a definite boundary to the kumquat love. I have never been able to reach the pistachio boundary.

No one else in the house likes kumquats much. Susy can choke one down, but that's it. Everybody loves pistachios. Even Mikey likes it Andrew likes them.

Moose likes bits of orange, so I thought he might go for the kumquat. He tried it briefly, then left it on the floor. The other day we were all (except Moose) playing cards (Euchre or Hearts) and I gave him a pistachio. He dropped it on the floor and stared at it for a long time. He kept coming back to it for the next hour, but only to stare at it, very hard - as if he was willing it to be some other type of food.
