Stubborn

"Never try to out stubborn a cat!" -Robert Heinlein

I am currently in a stubborn contest with my (loaner) cat. He is very fussy about his food. This is so much so that he wants to have a different flavor of food every time I feed him. I don't know if this is unusual because I've never had a cat before. I do think it is unreasonable. He needs to finish the can before I'll move on to the next one. That is the rule and I'm sticking to it. I don't mind changing flavors, but not mid-can.
