Castor&Pollux did not reply to my letter. I am, however, still feeding the Castor&Pollux Chicken and Vegetables Casserole. I KNOW the cats don't need those fruits and veggies, but they have to eat something, and the two finicky ones, one (The Kitten) who has a limited diet, both like it and The Kitten does not appear to have any digestive issues with it.
They get it most mornings for breakfast, and something else for the other meals. Every third or fourth day I stop feeding it for two or three days, because if I feed it too often they won't eat it at all. I just ordered another batch, with fingers corssed that this batch is a good as the last.
This seems to be a problem even in the high end foods, consistency I mean. Cats will eat a food with great enthusiasm, and then you open a new case with a new batch number and they won't touch it. When I pay a fortune for food, I expect consistency to be part of the bargain, they should not be changing suppliers of ingredients looking for the lowest bidder, so the food is always different. If I wanted that I'd buy grocery store food.
