Porus One Kidney Powder Supplement for Cats is a revolutionary product that contains Renaltec, a selective carbon-based adsorber specifically designed to target protein byproducts in your pet’s gut. These tiny, black spheres have a smooth surface and are perforated with pores that create a branched channel system, similar to the bronchi. This unique design allows for easy passage through the GI tract without adhering to the mucosa or accumulating in the intestine. Plus, this supplement is tasteless and odorless, making it easy to administer during mealtime. And with the NASC Quality Seal, you can trust that you are giving your feline friend a high-quality product.
