There has never been a report of a cat developing FUS as a result of being on a raw diet. Part of the reason for this is due to the well known fact that raw meat diets result in acid urine output and grain-based diets result in alkaline urine production. Acid urine is not a favorable medium for struvite crystals to form, so even if a particular cat may be predisposed to FUS, if the urine is kept acidic, the probability of crystals forming is low. Plus, the natural juices and water content of the raw meat diet insures some natural fluid intake, unlike dry cereal-based cat foods which dehydrate the cats, thus making the cat drink water all the time. The dry foods take the water away from the cats’ system causing them to drink even more water. Over time, this back and forth dehydrating and drinking of water will put a strain on their kidneys.
