I am using this product for a 20 year old cat, we only give half a sachet due to possible constipation issues, so use soaked pysllium husk with his food. Another of our older cats who has exhibited some renal changes is very happy to eat a whole sachet mixed into her food. I do not feed real food as it is full of things cats wouldn't choose to eat in the wild, but need to mitigate against the higher protein and phosphorous in the raw cat food we feed. I feel this product does an excellent job.

Product Description
Porus One
Support your cat’s kidneys with Porus One. Cats naturally produce toxins every day, some of which can be harmful to the kidneys. These toxin precursors (known as uraemic toxins) form in the gut during the digestion of proteins. When absorbed from the intestines, these toxins travel via the liver to the kidneys. They are normally excreted in the urine. However, if this process is disrupted, toxins can accumulate in the bloodstream. This build-up can cause direct damage to the organs and kidneys. Porus One acts like a kind of vacuum, binding the precursors of these toxins in the intestines. This allows them to be excreted in the faeces before they can enter the body.
Key features
- Supports kidney function
- Prevents absorption of toxin precursors in the gut
- Helps protect kidneys from toxin-related damage
- Toxins are excreted via the faeces
- Porus One consists of small, uniform black beads
Suitable for
Cats (including those with kidney issues)
Instructions for use
Give Porus One to your cat once daily. Mix the contents of the sachet with wet food to help it bind. Porus One is odourless and tasteless, so it is generally well accepted by cats. One pack of Porus One lasts for thirty days. If you are also giving medication, it is recommended to administer the medication at least 2 hours before giving Porus One.
Bead size
The black beads measure between 0.1 – 0.3 mm in diameter
Contents
- 30 sticks of 500 mg
- 6 x 30 sticks of 500 mg

Definitely recommendableBy Ricarda Klein, Thursday 5 November 2026Porus One - 30 Sticks
Our 13-year-old Ragdoll cat has early-stage kidney failure. That’s why it was worth trying the Porus One sticks along with the additional treatments prescribed by the vet. The dark powder mixes well into the food and is easily eaten by our cat. Whether it will make a difference in progressive kidney failure is questionable. However, it provides a good extra relief since the “toxins” are bundled and excreted through the intestines rather than the urine.
