What substance tends to build up as sediment in cats?

The substance that tends to build up as sediment in cats is commonly crystals. In feline urinary health, crystals such as struvite or calcium oxalate can precipitate in the urine due to various factors such as diet, dehydration, and urinary pH levels. The formation of these crystals can lead to urinary tract issues and discomfort for the cat.

Minerals can be components of these crystals, but the specific term "crystals" directly relates to the structures that form in the urine and lead to sedimentation. Therefore, while minerals contribute to the formation of these crystals, identifying them simply as "minerals" does not fully capture the problem associated with sediment in a cat's urine. Understanding the types of crystals involved and managing their formation is crucial for maintaining a cat's urinary health.
