Types of kidney stones in cats
Calculations, popularly known as "stones", are formed by the deposit of different substances in the urinary system.Those that form in the kidneys must reach the bladder to be expelled.As the calculations can be of very different sizes, this will determine whether or not its exit with the urine is feasible, or if they will be large enough to cause a total or partial obstruction in some point of the urinary system.
In its formation the pH of the urine is also very important, since it will influence whether it is more or menosacid or alkaline.Also, the calculations are classified according to its composition and on it depends the diet for cats with kidney stones.In this way, we will find the following:
- Struvite calculations : they are the most common.They are formed by ammonium and magnesium phosphate in alkaline urine.It is easy to occur after an infection of urine, since crystals can be deposited around bacteria.They also appear in young cats.
- Calcium oxalate stones : they are formed in acidic urine, in cats with a high concentration of calcium in the urine.

- Adding polyunsaturated fatty acids also reduces the formation of calculations.Kidney stones in cats should be rich in omega 3 and 6, although we can also add stiff foods to your diet as a supplement, always under veterinary supervision.
- It is advisable to provide the food several times a day.
