I heard good things about this specific food both from the vet and from other "experts". However, my cat had a different opinion. My efforts to honor her were in vain. On the first day, she nibbled on something. The rest of the days, nothing, even when I mixed it with the kibble she loves in order to gradually change her diet, she would pick out the kibble! She was stubborn. Maybe because she wasn't accustomed to fish from a young age. I had to switch companies. The plus side is the well-packaged and the fact that it comes in a small size for testing, while the equivalent liver foods from other companies start from 1.5 - 2 kilograms and if it's not ultimately consumed, you've wasted your money. The success of clinical food is to be tasty as well. Therefore, I didn't have the chance to see any practical difference in my cat's liver values or any pros/cons from consuming it.
