The secret of the Happy Miau® Technology

 How the technology of Happy Miau® works...

...that's what many people ask, especially since Happy Miau® seems to work like a miracle. What's actually in that cute little pink bottle? You'll probably feel a bit like you're in chemistry class now, but it's really worth reading through - you'll want to know what you're spraying around in the litter box and why it's so harmless!
Happy Miau®'s technology – based on NASA technology – is activated by sunlight or artificial UVA light, turning surfaces into light-activated air purifiers. Harmful organic compounds are oxidized and provide clean and odorless air in your cat litter box.

How is that even possible?!

Happy Miau® – containing Titanium Dioxide (Ti02) – is activated by UVA light after coating the litter box and starts a natural chemical process that uses oxygen (O2) and moisture (H2O) in the air to eliminate bad odors from the litter box. This process is called photocatalysis and transforms chemical substances under the influence of light. The Titanium Dioxide absorbs the energy of the light and transferrs it to reactive compounds, thus triggering a chemical reaction - often by the formation of radicals. Therefore, it is important that sufficient air circulation is provided and the litter box is exposed to enough UVA-light.
 
Fine, but what exactly is this so-called titanium dioxide?
Titanium dioxide (TiO2) is a mineral which is non-toxic, non-reactive and has a whitening property. It is used in various products that we use every day such as toothpaste, paper, medicines and food.

Now that we have clarified the most important points and have our ingredients for the magical reaction ready, it's time to get down to business. What happens now?

  1. Stale urine is converted by an enzyme into ammonia (NH3) and carbon dioxide (CO2). Ammonia is the toxic and strong smelling gas that causes the odor in the litter boxes.
  2. The UVA light hitting the surface of the litter box coated with TiO2 activates the photoactive reaction in which two powerful detergents are formed: Hydroxyl radicals (OH-) and superoxide anions (O2-).
  3. Superoxide anions (O2-) oxidize (cleave and neutralize) ammonia to nitrite (NO2-).
  4. Nitrite is then oxidized to harmless mineral nitrates (NO3-) or converted to nitrogen (N2).

So what is left and why does it no longer smell?

What remains from the reaction are NO3-, N2 and CO2, all of which are harmless to animals, humans and the environment. So there is nothing left in the toilet that could cause a bad smell.

You are probably also wondering what it has to do with the fact that the sand lasts about 30-50% longer. 

As mentioned above, moisture (H2O) is needed for the photocatalytic process. This can also be extracted from the liquid in the sand, which leads to the result that the sand remains dry longer and therefore needs to be changed less frequently.
