I feel like the arguments laid out on this website are pretty poor and border on nonsensical without sources to back up any of the claims. Are there any sources to back up any of the claims here? Why should we believe this?

To refute this website by googling I easily found a fairly well sourced article claiming that the two are basically equivalent and there’s no conclusive research showing dry food is worse for health: https://www.veterinarypracticenews.com/cats-and-food-septemb...

"Soy contains phytoestrogens and soy also negatively influences the thyroid gland"

Sorry, stopped reading here. Do you have a source that isn't verging on anti-science nutbar crap? Genuinely interested in the health benefits, but after reading that sentence I can safely say that any claims on that site are suspect at best. The only other times I've run across the soy/phytoestrogen argument have been from anti-vaxxers or Alex Jones level conspiracy BS. And the constant references to Man's ignorance definitely didn't help.

Yup, that kibble crap is no good. You (hopefully) wouldn't eat Bachelor Chow, why feed it to your pet? It's barely even a cost issue with cats, their body weight is so low compared to people.
