Royal Canin Veterinary Cat - Urinary S/O

I was forced to resort to this product for my cat who suffers from struvite. Even after a rather invasive operation, I continue to give him this product as maintenance. Four stars (and not 5) are because of Bitiba. The €5 increase (on the 9 kg pack) is really discouraging and not very fair, especially considering the times we're living in. We're talking about a product that's already very expensive. As for the product itself, nothing else to add. It's tasty and effective.
