so WHAT is a healthy ash/magnesium content based on dry matter of wet food?

I've been search for the answer but haven't come across it ... anyone?

I  found this info . I have no idea if this is fact or opinion .. Below  is the website where I found it ..

2.  Feed a cat food low in ash and magnesium. 

“Ash” refers to the total mineral content of a food. It gets its name from the laboratory procedure used to measure mineral content—burning a sample at high heat until nothing is left but the mineral ash. The major minerals calcium, phosphorus and magnesium are all necessary for life, so “ashless” cat food is not desirable. The right amount and balance of minerals are necessary. Excessive minerals, and especially excessive magnesium (a major component of the struvite crystals) are thought to be underlying factors in FLUTD. In dry foods look for less than 7% ash and 1% magnesium. In wet foods (containing 78% water) look for less than 1.5% ash and 0.02% magnesium.

thanks for that ...I assume this is as consumed ad not the dry matter - but it's helpful

Ya welcome .

Since the cans are going to state the Ash on an "as eaten" or Guaranteed Analysis basis, versus Dry Matter, that's what I go by.  And I look for something less than 3% Ash.
