Madame C keeps on surprising us when it comes to her selection of food.
Following, in order of appearance, the things that we encountered concerning Madame C's nutricious out-breaks and demands (the oldest entries at the bottom of the list)

The newest delicacy is maquerel, completely organic and naturally fished with dolphin-safe methods. Although this fuzzy pussy usually wrinkles her nose at foods made just for her. Instead she lunges at anything that looks like a potato chip or a nacho. Blue cheese, yoghurt WITH sugar and flavor, garlic cream cheese, everything goes. So we keep her belly in balance with letting her lick the tinfoil caps of our probiotic yoghurt drinks.

Since my conviction is vegetarian, I have a nudging feeling of guilt when I feed Cassandra the kind of food I myself find unethical to consume. So I have decided to experiment with shifting Cassandra's diet towards a more organic, ethical one, with foods that are not tested on caged animals (Almo Nature's canned foods, Eagle Pack's kibbles). I have also discovered horse meat and game. The first mentioned is usually killed because of old age, and thus it's life actually has a meaning other than becoming supper. The latter has had a free life and a chance for survival. I also give Cassandra by-products such as chicken throats and wings, hearts, tongues and livers. These are not only throw-away meat, but also of good nutritional value. However hard it may be to keep feeding her another living being's raw flesh, I do not want to resort to vegan cat-keeping, found in some American homes (unthinkable, poor, poor creatures!).

But then... We had to find out, of course, what kind of food she prefers. Anna's a rather ethical person, so she refuses to buy food that it fabricated with help of all kinds of animal-unfriendly tests and such. So we bought these little cans of "good" food, which have like 150 grams in it and cost a fortune. And do you think Madame C would eat it? Think again!
So at one point it happened that we were out of food for her and had to buy something quickly, so we ended up with one of those "not-good" cans, surely cheaper. It looked like crap, literally, and it smelled like crap, literally, and Madame C devoured it. It was gone in an instant. Truly incomprehendable!

First thing we were shocked to see was — when cleaning her litterbox — a neat pearl-chain of catdroppings, held together with one (or some) of Anna's long hairs. For some reason Cassandra seems to love chewing and swallowing down those long hairs, even if it might cause her some problems with doing her thing in the litterbox. However, that appeared to be one of the most common things with cats.
