From the second day, the house started to smell excessively. I kept it for 5 days, and instead of improvement, the smell became stronger and stronger, as I assumed that the cat was doing its business outside the litter box. Just one day after replacing it with another food, the smell disappeared.
Maybe it was just my cat, but I can't recommend it to anyone else.

Update: A few days later, the smell disappeared. Perhaps the change in food, although done gradually as it should, affected my cat's gastrointestinal tract. Anyway, after the first week, things are much better.

The vet recommended it to me and it is indeed very good. Normal bathroom rhythm and soft fur.

*UPDATE
I still have the same opinion, but now I have switched to BARF food (Volddog) and I'm not changing it. When I have to give him dry food (it's the only one I have available), his feces smell awful. With barf, they are completely odorless.

I read in many reviews about cat food that the cat eats the food with a lot of appetite. This is in no way a criterion for the suitability of the food, just like the choice of pizza over legumes is not a criterion for us humans.
In this case: it is an honest cat food that does not offer more than it promises, but at the same time it provides more than its price suggests. At first, I thought that my pet did not like it because of the small amount it consumed compared to another brand's product. However, I quickly realized that my cat was simply satisfied with a smaller amount of food, resulting in odorless and compact feces.
Therefore, yes, the product is worth it, but for God's sake... give the living creature some fresh sardines or anchovies... healthier and cheaper..
