They’re doing something right.
My BSH kitten arrived from the breeder along with a bag of this kibble. I wasn’t happy with some of the ingredients, rice, maize, unspecified ‘poultry’, so tried a Thrive kibble, which gave my kitten constant bloating and diarrhoea, so put him back on this food, and he recovered, and is back to normal, I’m sticking with RC!
