Hi Deborah, I totally understand the concern, I have concerns too.
Did I say I planned to add the supplement to a commercial food? That's not my goal here. The problem is that I've been feeding commercial raw to the boys since day 1, but Dante is often resistant and a picky eater. So sometimes I sneak him a can of Weruva here or there, which is essentially chicken breast with vitamins thrown in. But I hate the single-serving cans (and the cost of the cans) and don't trust Weruva to use high quality anything, and processing in Thailand, and guar gum and carrageenan and--I think I'm just suspicious about every company these days. (Every company, most vets, the FDA, ugggh nobody is helpful or useful lol except maybe the people here

) And to top it all off, although Duma is fine with his raw food, he goes bonkers for Dante's cans, which makes me even more suspicious that there's something junk-foody about them, and also forces Dante into the bathroom to eat in peace.
As a result, sometimes, if I'm cooking a chicken, I'll give some of it to Dante for a meal. (Duma generally prefers his raw to the cooked chicken.) Then when I saw BalanceIT, I was thinking, well isn't that what I'm doing already? The idea behind it is cook up a chicken and add a supplement, which has to be far better than what I'm doing now, just giving him chicken alone? Certainly that is unbalanced...even if it's only a once in a while thing. I could just make it a full time thing for him?
That whole "individualized for your pets needs" idea seems kinda stupid to me, I mean BalanceIT is not going to provide any less of an individualized diet than Weruva does, no? Aren't all cat foods standardized? I mean, even Science "medical" diets aren't individualized, no matter how hard they might try to convince you they are. They're still providing a generalized product that tends to have more of X or less of Y.
So essentially what I'm thinking of doing is following a BalanceIT plan for Dante. They have a recipe that is essentially "Cook a chicken and a sweet potato, mix them together with some oil and this supplement." My intention is to feed Dante this diet (or at least a diet based on one of their recipes), not to mix it with commercial diet.
I'm not sure if I'll switch Duma over to a BalanceIT diet, as he seems to love raw.
I hope this clarifies what I'm planning to do. If you still think I'm crazy, please feel free to tell me so--I won't be upset. I really need to make sure I'm covering my bases here. I just want to do what's right for my boys.
