Just add extra Taurine, and add digestive enzymes, and it should be be fine. You can't harm them with more Taurine - you can get powdered taurine at any good heathfood store. Digestive enzymes are important too (pro/prebiotices). Just read the labels to make sure there aren't any bad ingredients for kitties.
Don't forget you are comparing this to the wonderful commercial food. "Food" that is NOT inspected by FDA. "Food" that we are taking on faith that the producers are being honest about the quality and ingredients. Of course these commerical producers CARE about our pets and want what's only best for them. Making as much money and as big a profit margin as they can get is NEVER in their minds! Pet parents as a whole MUST get out of the mind set that just because the bag/can says it's complete and balanced, doesn't mean it is!!! This is ADVERTISING to sell as much of their product as they possible can. As for Vets, they are human and fallible and gullible like all humans are. Do you trust everything your human doctor tells you? I hope not. When I started the peri-menopause thing, my human doctor tried to push hormone therapy for all the wonderful side effects I was having. I chose to try soy and vitamins. I am doing great. So now the perfectly "safe" hormone therapies are coming under attack for a tremendous increase in breast cancer in women. Not to mention all the other potential risks. They also torture horses to make it. Lots of vets now are finally seeing that homemade isn't bad. Sorry - off my soapbox now!
Yes, raw is healthier, but some cats can't tolerate it, or would rather starve than eat it, and for some folks its not do-able.
Puddin eats raw chunks. She won't eat raw ground. She gets raw chickie junks, with raw turkey heart and chickie liver chunks mixed in. I do mix in some taurine powder and powered egg shell, and a bit of powdered kitty multi-vitamin in the juice. She gets that for 2 meals a day, then the other meals she gets cooked home-made. She is the 10+ year old kitty we adopted in December who was 1/2 what her body weight should normally be. She had totally liquid diarreha and spent a week at the vet hospital. After 3 months, she is 10.3 pounds. Her fur is soft and silky. Her teeth are beautiful - whiter than mine are (her people drink lots of sweet iced tea). Her stool is perfect. Tell me raw is bad... She will not eat canned food - she looks at it like its garbage.
I am trying very hard to get our other cat, Tumper to eat homemade cooked. He can't eat raw. Comes right back up. He has a very sensitive tummy due to severe IBD when we adopted him 7+ yrs ago. He is not a foodie, and I believe would get close to starvation before and if he would give in and eat something that he hated. Unfortunately, I have to still feed him canned, otherwise he wouldn't eat at all! I am working on sneaking in homemade cooked w/his canned little by little.
