If a cat has a normal urine pH level of 6.5, how would this level be classified?

A normal urine pH level of 6.5 in a cat is classified as mildly acidic. In general, a pH level of 7 is considered neutral, with values below 7 indicating acidity and values above 7 indicating alkalinity. Since a pH of 6.5 is below neutral, it indicates the presence of excess hydrogen ions, which is characteristic of acidity.

Mild acidity is a common state for feline urine, as it helps to prevent the formation of certain types of urinary crystals, which can occur more readily in alkaline urine. It is important to note that a significantly lower pH would be considered highly acidic, while a pH closer to 7 would be more neutral. This contextual understanding highlights why 6.5 is categorized specifically as mildly acidic.
