8 Best Cat Kidney Supplements in 2023 – Reviews & Top Picks

As our beloved cats age, their bodies start to slow down and struggle to keep up with the tiresome demands of the life of a domestic cat. Organs become worn out by natural decline, and often the kidneys tend to be one of the first to begin struggling, with 30% of cats over ten years of age suffering from chronic kidney disease. If your cat battles with declining kidneys, your vet will arrange care that may involve special diets or medications, but this can also be supported with the use of supplements. Supplements can also be used for general health and preventative care for cats of all ages. With a wide array of products on the market, it can be hard to know where to begin, and you want nothing but the best for your feline family member. We’ve compiled a list of the most effective cat kidney supplements for which many cat owners give glowing reviews.

A Quick Comparison of Our Favorites

The 8 Best Cat Kidney Supplements – Reviews & Top Picks 2023

1. Vetoquinol Epakitin Powder Urinary Supplement – Best Overall

This supplement is the best overall kidney supplement for cats due to its proven efficiency in slowly CKD (chronic kidney disease). Other products from the same brand are also highly related to supporting kidney health, but this is the only one that acts as a phosphate binder. Blood phosphorus can remain high in ill cats even when they are on specifically formulated kidney health diets with low phosphate. This is due to the over absorption of phosphate. Phosphate binders such as Chitosan bind phosphate cells to reduce the amount absorbed through the gut wall. This product is highly reviewed with testimonials of excellent results as use as a kidney supplement. It is also suitable for dogs and cats, so if your dog tends to eat your cat’s leftovers when you aren’t looking, then no harm can be done!

Key Considerations

Kidney Disease in Cats

Kidney disease may arise in cats of any age but is more prominent in elderly cats over the age of 12. As a cat’s body ages, many organs can become tired and inefficient; the kidneys tend to be the most common. Cat kidneys keep their body in homeostasis by managing water and electrolyte levels and removing waste from the blood. Early signs include excessive thirst and strange urination habits such as frequent and large amounts. As the kidney and urinary health declines, toxins can build up in the blood and cause general illness and discomfort. Kidney supplements can provide support in preventing kidney disease by maintaining general health and vigor. Combined with special vet care, medication, and diet change, supplements can also help treat kidney disease and failure. Supplements help cats by providing them with essential nutrients for normal healthy kidney functioning. Many supplements will lower the inflammation involved with poor functioning kidneys. While supplements certainly have their benefits, you should consult your veterinarian for specialized support if your cat displays signs of illness or discomfort.
