protein questions

[Mike Cavanaugh]

The cat food is a bit too high in fat and protein and may ruin their kidneys.

Thanks for the replies!

I will look into the hog feed... but that won't be very easy to get here.

Keep in mind, I am thinking feeding mostly Mazuri 6f with some cat food mixed in. here are the numbers. Do you think this would cause kidney trouble?

Mazuri 6F -
Crude Protein 16%
Crude fat 6%
Crude Fiber 5%

Mazuri 9F
Crude Protein 16%
Crude fat 9%
Crude Fiber 5%

Purina Cat Chow Indoor Formula
Crude Protein 30%
Crude fat 9.5%
Crude Fiber 6%

Granted, I have no idea what I am talking about here, but with that said, the formulas all look very similar... the cat chow appears to be like the mazuri 9f, but with twice as much protein.

So if I feed primarily Mazuri 6F and mixed in some cat chow... would that be the same as feeding mazuri 9f plus some extra protein? Or am I looking at all this completely and totaly wrong?
