Of humans and diets

Dear George,  
Mi chiama Luigi e io sono Italiano. At least I think I’m Italian since I was rescued by an Italian family.  And you got it….my name is Luigi and I think I’m about 3 year old (I don’t remember much of my life before being rescued). Well, all was great until the other day when my human kitten bragged about me to some crazy lady. Why crazy? Because the minute she heard I’m a 22 lbs. cat she started lecturing about me being too fat (how does she dare) and that I can become diabetic and all that nonsense.
Now, you should know that I am a big cat and I am….hm! well rounded (as you can see in the picture) but, I think I’m far from being fat. She advised my humans to cut off completely the dry food and to give me only wet food and only twice a day.
George, I’m not only in a state of shock but absolutely worried that my humans might take her advice. Am I going to be starving? I think she’s so crazy that she would put anybody (humans and cats) on a diet. What is wrong with these people? I don’t tell them to cut down on their pasta or red wine or cheese. George, is it true that we can become diabetics if we eat too much? Since humans are so obsessed with diets….what is a proper diet for a cat? 
Confused and mad
Luigi

Dear Luigi,
I share your irritation with humans. Have you looked out of the window lately and seen those HUGE humans lumbering by. Twenty stone or more of male and female flab. And they have the cheek to lecture us about getting fat! I see my human eating varied and delicious meals, while I have to get by on the same cat food (albeit of a different flavour) each day. It makes my blood boil.
I have to put up with a vet (whom I naturally loathe anyway) who lectures Celia on keeping my weight down. She's quite unpleasant about it: making personal remarks about the saggy state of my tummy. So I am on a restricted diet. Luckily for me I can supplement it by going out there and eating mice and baby rabbits. For cats with a cat flap, I advise doing this or just raiding other cats food by entering their cat flap.
If you are an indoor-only cat, this isn't available to you. What your human should be doing is to give you a more interesting life in order to boost your exercise quota. More fun instead of just less food. Ignore the advice about wet not dry food (unless you have a medical condition like cystitis). Get rid of the boring food bowl. Put your dry food into food dispensers (read How to Have a Happy Indoor Cat here). Scatter the food round the house so you have to hunt for it. It's not such good fun as hunting mice, but it is almost as good. Lots of games with fishing rod toys.
I might say that this should apply to humans too. Less time in the shopping malls and more time in the gyms or out on the hills. I push Celia out every Sunday to walk for 4 hours while I get on with the hunting. She complains but it does her good.
A fun-not-food-deprivation diet is what you need, Luigi. 
Yours 
George
