with app. 1/3 fat 2/3 proteine in the meat part of the food - but no or
only very little carb) seem not to know this! ;-)
A while after I had changed my cats to raw food they reduced the amount of
food that they eat a little bit. So they each eat about 150 - 200 g food
(not meat, but the completely prepared food including all supplements and
water) per day, and they gained some weight due to more muscles (even
Tonya, who ate her first raw diet when she was already 10 years old), but
they did not get fat at all.
I'm always astonished how much fat is in some normal brands of cat food.
Have you had a look at Felidae (just as an example)?
Felidae dry food has 32 % raw protein and 20 % raw fat.
Felidae canned food has 11 % raw protein and 7 % raw fat.
Wouldn't you give such food to an altered cat normally? Well, my raw diet
has relatively less fat, though I try to feed meat with as much fat as I
wouldn't want to eat myself in meat ...
It's a longer time ago that I read Deb Zoran's articles, so I don't
remember them precisely. It's only that I know a lot of altered cats on
raw diet in Germany who get meat with app. 10 % fat. And if you keep in
mind that meat (/ fish) contains 10 - 30 % proteine, then 10 % fat results
more or less in about 1/3 fat and 2/3 proteine in the meat - which results
in app. 50 % of the calories coming from fat and the other 50 % coming
Since fat has a lot of positive sides as well (for the digestion, hair and
skin quality, calorie source that does not produce urea, ...) I would
always try to start with a diet with 1/3 fat and 2/3 proteine (I don't
count carb since I only use as much of it as needed as fiber for a good
digestion). For a cat with kidney problems I would give more fat, for a
cat with liver problems or a really great tendency to become fat, I would
reduce the fat part in the food a little.

Remember that I am quoting what Deb was stating in a presentation this past
summer at a veterinary conference held here. When I mention altering, (aka
gonadectomy), I am quoting what she was saying to the vets, (the few that
turned up to listen to a nutrition related speach), and for me, the equation
of altering a cat to humans going through stages of life where hormones
change made sense, just as it appeared to for the rest of the audience.
There are studies out there, done recently on cats, showing the changes in
leptin levels with what is usually referred to as "gonadectomy" in the
abstracts if you are looking for them. Another hormone she didn't have time
to touch on was ghrelin, for example, which is also receiving a lot of
attention at present in human RDA circles. Deb's presentation had a whole
pie chart shaped graphic showing a number of hormones related to
age/gonadectomy and obesity.
There are also studies connecting higher serum lipid count with insulin
resistance, (see below). I wasn't taking Deb's word for it, even though I
spent a major amount of money to listen to the best resource on feline
nutrition that will probably ever pass our way.

The information she was passing along was supported by very recent research,
so what she is saying now may not match what you remember from the past. I
was given permission to pass along the outline for her presentation but
don't remember if I put it in the Files section of the Heart group or not.

We have to watch carb intake as we have a diabetic cat in our midst. As I
always like to know the science behind statements I looked up some of the
information on carbohydrate intake that Deb mentioned should be "moderate"
accompanied by the low fat, and found studies such as the following:
"These data provide evidence that in cats, high dietary fat, but not
carbohydrate, induces weight gain and a congruent increase in insulin, while
GX increases sensitivity to weight gain induced by dietary fat."
"No post-prandial hyperglycaemia was seen in the 10 diabetic cats during a
2-h period following the ingestion of typical cat foods. "
These studies confirmed what we have seen in Hamlet's glucose curves with
his frequent small meals:

Personally I would like to see the science behind the choices before making
them for our boys.
JMHO.........Pat and all the boys.
