Male cats are far more likely to form urine crystals than females but that doesn t mean females can t be affected. Crystalluria is a medical condition where crystals are expelled into the urine. It was formerly referred to as feline urological syndrome or fus. Interestingly these crystals used to be extremely rare but now account for roughly half of feline urinary crystals.

These crystals can be observed under low magnification particularly when seen in large number however low numbers may only be seen at higher magnification. Flutd includes crystal formation in the bladder which might obstruct the cat s urethra. If the crystals form in to stones diets are not effective at dissolving them and they require more drastic intervention. Some normal animals can have crystals in their urine although sometimes they are indicative of an underlying issue especially if present in large numbers or accompanied by urinary symptoms.

Struvite specifically is a material that is composed of magnesium ammonium and phosphate. In some urine samples they do not have irregular protrusions but have smooth borders and can resemble calcium carbonate although these do not occur in the urine from dogs and cats. The crystals themselves can be perfectly normal but become problematic when they combine to form grit or stones of varying shapes and sizes.
