Description Porus One binds protein byproducts in the intestines where they are excreted in the feces, which helps to prevent the byproducts from being converted into uremic toxins. This product supports kidney health in cats. Each packet of Porus One contains Renaltec, which is a selective carbon-based absorber of protein byproducts in the gut. How is Porus One used? Porus One is tasteless and odorless, and can be easily administered to cats once daily at mealtime. If your feline patient takes other oral medications, those should be given at least two hours prior. It is normal for a thin layer of Porus One to remain inside the packet. Has Porus One been studied in cats? In an 8-week study of 18 healthy geriatric cats (11 to 16 years of age), Porus One was shown to be beneficial for kidney health. Twelve cats received 500 mg of Porus One daily and six cats served as a negative control, receiving the same type of food as the Porus One group. The mean serum indoxyl sulfate concentration was reduced by more than 60% in the Porus One group while no significant change was observed in the control group. Porus One was also readily accepted and well tolerated by the cats.** **Mottet J, Kowollik N: BSAVA Congress Proceedings. 2019. 424-425.
