Specific FSD & FSW Struvite Dissolution is complete and balanced diet which, due to the reduced amount of magnesium and phosphorus, is especially composed to help with the prevention of struvite stones and crystals in adult cats.The precipitation of struvite (magnesium ammonium phosphate) in the lower urinary tract is promoted by high concentrations of magnesium, ammonium and phosphorus in the urine and an alkaline urinary pH. Struvite Dissolution also induces a low pH, which will prevent the formation of struvite.

Omega fatty acids EPA and DHA are present to help support a healthy skin and coat for the cat.


  • Struvite dissolution - The diet has a reduced content of magnesium and phosphorus (components of struvite crystals) for dissolution of struvite stones and reduction of recurrence of struvite crystals and stones
  • Urine pH control - A urine pH at 6.0 – 6.3 dissolves existing struvite crystals and minimises the risk of precipitation of new struvite crystals
  • High urine volume - The increased sodium content promotes that the cat will drink more. This is associated with reduced urinary mineral concentrations and increased urinary frequency
  • Skin, coat & joint support - EPA and DHA are both omega-3 fatty acids with a beneficial effort on the maintenance of healthy skin, coat and joints

Although this product looked rather nice to me, I'm afraid my cat did not agree! I'm sure it would have been effective if I could have persuaded him to eat it, but in order to do so I had to mix it with so much ordinary food it probably wasn't worthwhile. He's a fussy beast.
