And Katie gradually chowed her way through the can, misbehaving all the way. *sigh*
Last night, I picked up the empty can and carefully read the list of ingredients again, looking for anything suspect. The last ingredient on the list was "annatto color extract". So I went off to Google and found that a number of people have bad reactions to it, which might just explain the way Katie misbehaves after eating it.
(This is not to say that I trust everything I see on random websites that I google up, but rather to say that I'm willing to let them confirm my own observations from time to time.)
So just because it's a "natural" ingredient, it doesn't mean it should be on Katie's diet.
And from now on, it won't be.
