Cosma Extruded Duck Dry Food

The cat likes the taste and eats it willingly, but to his own detriment. Even after a few weeks of gradually getting him used to it (mixing it with his previous food), he had slightly looser and smellier stools (but that can happen when switching to a new food, so I gave it a chance). Once I started feeding only this food, he immediately developed really foul-smelling diarrhoea and would cry before going to the toilet. I switched back to the old food as quickly as I could. + The cat enjoys the taste + Doesn’t have a strong smell from the bowl - Really smelly diarrhoea once or twice a day

Unfortunately, my cat gets diarrhoea every time he tries this dry food.
