Quite easy really

You take all of the macronutrients (including water) - so that is moisture, protein, fat, fibre and ash - and subtract them from 100, which will give you the carb content. But to get a better measure of the carb content, you then need to convert this to the dry matter, which means subtracting the moisture

For example

Grau (Poultry with wholegrain rice)

Protein = 10.5%; Fat = 5.5%; Ash = 2.5%; Fibre = 0.3%; Moisture = 79%

So 100- 10.5-5.5-2.5-0.3-79 = 2.2%

To get the dry matter of that carb content you need to subtract the moisture from 100; so 79 - 100 = 21. You then divide the carb content of 2.2 by the 21 so 2.2 / 21 = 10.5. So the Grau contains a carb content of approx 10.5% at DMA.


Compare this to Animonda
Fibre = 0.5%; Ash = 1.4%; Protein 11.5%; Fat 5.0% and moisture 79%

So, the carb content is: 2.6 or 12.4% (2.6/21) at DMA.

The carb info (for both crude and dma) is also in the A-Z list that is linked to in the sticky in this section. Though some of the info is not out-of-date.

Hope that helps

Peculiar though as per their analysis, nought has changed at that level. Have you checked whether they have changed their filling facility because it could simply be that they are now using a different factory that is making it slightly differently.

Ianthi, that is weird but I have to say I have often had congealed fat in the bottom of some of the tins ever since I started buying AC, probably over a year ago now, so I can't see any difference at all. It could be the way I store them or something and if as Hobbs suggests the factory has been changed they might store them differently so that could be it?

The fat residue has been at the bottom of the tins since I started using this brand back in July. I haven't found it to be any more or less in either the old or new tins.

I do know that my cats love it though and I have to make sure that I divide it up evenly between the four of them.

I also believed that fat was less of an issue in a cat diet due to their biological make-up....

Thanks Hobbs! I just dismissed it at first as being the batch of meat used and wasn't too surprised considering it was the beef and lamb variety. Of course now this appears to apply to all the flavours I've opened so far!

Good idea about the checking since consistency and appearance have definitely changed! Never noticed any visible fat before.

Hi Shimmy,

The only thing I would add to Hobbs' post is that most experts consider that Carbs should make up about 10% maximum of a cats diet. Most good quality cat foods are around this figure, you may also need to consider that sometimes the analysis is different for different flavours for example one of the foods I'm feeding at the moment the duck flavour has only 6.8% carbs DMA whereas the poultry flavour has 23.7% DMA!

In many dry cat foods and even some poorer quality wet foods this percentage is as high as 30-40%+.

MG and Wellsandmittens - Just seen your posts. This IS very strange then given my experience up to now. I've just had to scoop out about 5mm of fat before I rinsed out the tin. I'll have to heat them up in future and see if it makes a difference!

Thanks Ali, I take on board your comments. I dare say that I may be getting slightly obsessive to reduce the carb intake for my girl, who is at 5kg at the mo, with 3.6 being healthier, and bearing in mind that for the last year her diet was Felix As good aIL, and GoKat/IAMS dry, I dare say that the Carny, wet only...is a big step in the right direction.

I notice that more or less all the recommended brands from the good doctor show low carb levels, though I note that they may have changed since the original sticky post. Grantapet/macs/pfoten and tigercat look good to me, so will have a good gander at them.

Hobbs...Thanks for the Carb equation, finally got my head round that and it is very helpful. Also, I didn't realize the original wet food sticky was still available and just read through it with interest. I note that the info may well have changed, but as a general guide on understanding cat food and nutrition it is a superb piece of work. I, like others, thank you for it!
( ps, assuming of course that you do know what you're talking about...otherwise we're all b******d!)

My last two batches have had much more fat in them actually. I have also had quite a bit of solidified fat in the bottom of the tin. But i've only had two varieties noticed the ones with the green label (not at home so can't remember flavour) as well as the heart plus are new recipe but most of my flavours have had lots of fat.
