I kind of sort of remember reading that post and I just put it down to someone being confused.
There are so many different formulations of dry food and wet food with extremely difffering pH levels that I think a blanket statement like that is silly. Plus the fact that with some foods even if the food itself is very acidic your body metabolizes it as alkaline.
So to say that Little Friskies dry + El Cheapo wet has the same effect on urine pH as Innova EVO + California Natural wet seems a little too much of a generalizatiion to me.
I could possibly understand that wet food contains its own moisture and so doesn't affect a bodies mineral content during digestion, and dry food causes the digestive process to extract water from the body to metabolize and so affects minerals.
I also understand that raw foods require a different set of gut bacteria to digest than dry food, and that the two shouldn't be combined at the same feeding.
It's like humans- fruit digests very fast, so you really shouldn't eat it with foods that take longer to digest. If you do the fruit just sits there and ferments while the other foods are still being broken down, so indigestion results.
Maybe that's the source of the caveat about dry and wet together?? Wet processes much faster and dry takes longer so indigestion is more likely when they are mixed?
Still doesn't affect pH, though.
Maybe that poster will show up and cite us something regarding the pH issue. I feed wet and dry separately, but purely from a spoilage standpoint.
