Splitting hairs, surely? Even pet food manufacturers will happily tell you a cat is an obligate carnivore. Judging by the rest of your post I think we're on the same page regarding the correct diet for them and it isn't high in grains.

Just a note though (I've raw fed for a lot of years and am well past the panic stage)... Yes you need to feed more than one protein source, but my original post said AT FIRST. A cat isn't going to die (or even become faintly mildly ill) from malnutrition in less than the week it takes to adjust to raw. You can add as many protein sources as you like after that.

Too much is made of 'complete and balanced' for pet diets, you can read more about that in Dr Tom Lonsdale's book "Raw Meaty Bones: Promote Health" or "Work Wonders: Feed Raw Meaty Bones". If you have children (if not, replace 'child' with 'yourself'), do you sit down every time you feed them to make sure they're getting a complete and balanced diet? LOL No you just feed a variety of species-suitable foods and over time a general balance is reached. You certainly don't sweat over the taurine, selenium, vitamin C or other nutrient content of each and every meal. Just feed a variety of fresh foods, and nature does the rest.

It's the exact same with dogs, cats and ferrets; and that's not me talking that's Dr Lonsdale, so please don't think I'm just trying to be clever or fatuous as I'm really not. I'm just saying don't become too worried about these things as they're not as big a deal as the pet food companies like to make out. Unfortunately, however, this worry seems to have become ingrained in the pet-owners' psyche by now, and it's hard to shift.

"OOHH!! Pet nutrition is rocket science! You couldn't POSSIBLY trust yourself to do it at home. Pay us and get '100% complete and balanced' food instead!!".

So why do we not have to buy 100% complete and balanced food for our children? After all, nutrition is so difficult...

However do they come out with 'new and improved formulas' every few months (check their adverts) if it was '100% complete and balanced' to begin with? Just a rhetorical question for your amusement.

Taurine is found in high levels (plenty enough for a carnivorous animal like a cat to remain healthy) in fresh animal meats and heart. Feed those and the cat will be fine.
