Everyone has cats with odd food habits. Neither of mine will look at fresh-cooked fish. One of them loves chicken — except when she doesn’t. The broth from a can of tuna is incredibly exciting — except when it isn’t. Food that has fallen out of the bowl will be treated as if it did not exist.
Cat owners know that it is hard to predict what the little furball is going to be interested in at feeding time. They know from experience that if “Sea Captain’s Revenge” has been popular for the last two days that you would have to be nuts to go out and buy ten cans of it. Cats are completely aware of how many cans you brought into the house and will starve before they touch another bite of it.
