Good manners means starting at the nose not the tail.

Dear George, 
I wonder if you can help me with my human. I believe, if what I read on your admirable blog is representative, that she is not really any more stupid than the average for her species, but she seems unable to understand the correct procedure for eating wild food. My mother, a cat of impeccable manners and breeding, taught me that the correct way to eat a rabbit is to start with the head. Then, if your appetite is delicate, you can leave the body to be shared by your family. Amy Vanderbilt’s invaluable Complete Book of Cattiquette confirms that this is how prey is consumed in the best circles, and I have followed her additional advice to leave an eyeball uneaten for “Mr Manners.” My human seems unable to understand this basic concept and keeps asking me why I eat the head first. She seems unsatisfied when I tell her that this is simply the right way to do it. How can I make her understand? 
Yours ever,

Dear Scaramouche,
Humans don't understand fur. They don't have any (except for some long fur on the head and some in the pits and pubes). Males have a few bristles and that it that. But mice and rats have fur - lots of it. If you eat it from the head first, the fur lies down flat. If you eat it from the backside forward, the fur gets ruffled up and makes it difficult to eat.

So it's not just good manners to eat that way: it's good practice. I do know of a bad mannered cat called Toby who starts in the middle. But he has lost 7 teeth and grew up on the street. You can take a cat out of the slum but you can't take the slum out of the cat. 
Keep up the good manners.
Yours respectfully, brother,
George.
PS. I leave the scut of a rabbit for Mr Manners.
