Has your poor kitty been suffering from a condition known as feline chronic kidney disease (CKD)? Then you must have heard your veterinarian mention using phosphorus binders to help remove excess phosphate from your cat’s blood.
In a Hurry? Here are Our Top Choices
The kidneys of cats that are suffering from feline CKD are unable to filter out excess phosphate salts from the blood. Phosphate is a naturally occurring mineral in foods, especially in meat and dairy products. In case of CKD cats, even a small quantity of phosphate in foods can become harmful because the kidney is unable to filter and excrete excess salt not needed by the body. A high concentration of phosphate in blood can result in hyperphosphatemia. Hyperphosphatemia reduces calcium levels in cats and their bone development could get affected.
Therefore, it is best to control phosphate levels in your cat’s blood as soon as they have been diagnosed with chronic kidney disease. The simplest way is to add phosphate binders to your cat’s diet. Continue reading to understand more about phosphate binders and discover the best phosphate binders for cats.
What are Phosphate Binders?
Phosphate binders are chemical components that restrict the cat’s blood from absorbing phosphates present in the food. The phosphate binders that are formulated for cats include aluminum or calcium salts, chitosan/calcium carbonate, sevelamer hydrochloride, and lanthanum carbonate.

These salts bind together with phosphate present in the food and lower the serum phosphorus level. So, once your cat takes a phosphorus binder along with its food, the chemical complex present in your cat’s blood will be high in calcium and low in phosphorus, as the calcium carbonate salt has now been mixed with phosphate salts from the food.
