Our cat came with 9 months with acute gum problems. It is Siammischling and lt. Vet thus still biased. Since then she gets sensitive than dry food orally. Lately I mix it because of the other cat that has problems with fur bales, with the "Intense Hairball" Royal Canin and the effect is great! Were the gum problems in Cat 1 story quickly, the situation of cat 2 improved now also sustainable! If she has to vomit times because she is behind quickly fit. Before the dry food of RC they agonized around 1-1.5 days. (You can not be lifted or touched by strangers, then she gets panic. We have them from the shelter and they must have previously experienced traumatic conditions. So we can not bring to the vet, but she has won much confidence and one day will still work ...)
I can highly recommend the food! While it's not cheap, but the well-being of our two noses, it is worth it! :)
