I was reading this site http://catsndogsnaturally.com/?p=219 when searching for how much Taurine a mouse contain
According to the site, it seems that there is a big difference in feeding whole meat with bones and supply with organ meat, and feeding ground meat that seems to be the foundation for the proof that cats don't get enough Taurine and vitamins/minerals/etc.
There is a loss of Taurine when freezing (mostly when defrosting)
There is only a slight decrease in taurine when the meat is frozen. However, the longer the meat is frozen, the higher the decrease in taurine. Taurine is water soluble and during the defrosting of meat some water is released, so the actual meat might end up with a little bit less taurine when thawed. But this loss of taurine is not caused by freezing but water release with some taurine dissolved in it.
but it seems as there is more Taurine in many meats than in a mouse (I'm terrible at math so let me know if I'm wrong) so it should make up for the defrost loss unless it's ground rabbit
Lets take a look at the taurine content of some meats:
Raw rabbit meat has the minimum requirement of natural taurine at .07 percent. And, raw chicken has a high taurine level of .12 percent. 1 oz. of beef liver contains 2.359g taurine per kilogram of dry weight (19mg). And, chicken liver contains 6.763g per kilogram of dry weight. 1 oz. of raw turkey leg has 86 mg. Chicken neck 33.1 mg. A typical mouse will contain 2.4 mg/g taurine or (for better comparison with the other values: 100g would contain 240mg) 4 ounces of a mouse would equal over 2400 mg taurine. So, you see, you don’t have to worry about taurine levels being deficient in raw meat (NOTE: Taurine is at its highest level in the tiny heart muscle of a mouse).
About the ground rabbit experiment the site says
Mind you, the researchers were feeding the cats only raw ground rabbit meat. And, as I mentioned above, raw rabbit meat contains the minimum amount of taurine to sustain your cat. Now, add grinding to the equation, plus, freezing and thawing, and taurine falls below the minimum requirement.
I get the impression from reading the above study that the researchers may have been trying to discredit raw feeding to cats by hinting that raw food was not as nutritionally viable as commercial food with its added synthetic taurine. But, the researchers have missed the whole point in feeding raw to our companion felines. The idea behind feeding a species appropriate diet of raw whole prey is to get as close to the cat’s natural diet as possible. The human pet owner can’t match it exactly (it’s not like we’re going to bring home live rabbits and chickens and expect the cat to hunt, kill, and eat the prey in our living room). But, what we can do for our cats is give them a rotation of various whole-solid pieces of fresh meat (rabbits, chicken, turkey, quail, mice, etc.), organs, bones, and limit the length of time the meat is stored in the freezer, and more importantly, do not grind.
I have been feeding my cats raw chicken with bones and sometimes raw chicken liver/hearts.
(They eat the small bones, and leave larger bones that are too big for them to chew)
I do freeze and defrost, but it is never frozen for longer than a week or two.
Unless the site is wrong, it seems as the diet they get is good, so I wanted to ask Z if you with this info still think it is best that I buy a meat grinder (very expensive) in order to grind the meat and bones (which will decrease the Taurine etc. levels and is not as healthy for the teeth as eating whole meat with bones) and then buy Taurine and other supplements to add to make up for the loss, and having to spend more time making cat food?
I really want to provide them a healthy diet, but if it ain't broken, there is no reason to spend money and energy to fix it.

Well, as far as I know, taurine, for example, should be added anyway, especially if you feed with ground meat. Unfortunately, unbalanced raw diet is worse than feeding with kibble.
Here's another good site about raw feeding.
says:
If you regularly feed ground raw to your cat (which I do not recommend unless your cat absolutely will not or cannot eat bones), then it is advisable that you supplement with taurine using either fresh beef heart (unground) or a commercial taurine supplement.
Which suggest that the diet I feed wouldn't need added supplements
The unbalanced raw diet that many warn about, is as the site Keit provided here

Dr. Karen Becker's article that can give you an idea. If owners can't mimic perfectly by raw food only all the nutrients a cat would require (such as Taurine), there is a need in supplementation.
says
Some pet owners believe they can offer their dog or cat a chicken breast and some veggies, and call it a day
but whole chopped up chickens with bones, and supplied with chicken heart/liver is very different from a chicken breast and some veggies.
What do you think?
As for getting cats to eat raw meat and bones, my experience is that well fed cats have quite different tastes (what one loves another hates), but being hungry helps a lot in making anything seem yummy. My cats don't like chicken wings much. The skin is very hard to chew through and there is not much meat as a bonus for chewing through it, but before they were my cats, and were hungry strays outside my house, they would swallow the whole thing, and so will the other hungry strays from the area, that have heard that there's a crazy cat lady living here who can't refuse a beggar a meal, and have started snoopin 'round my door...
