I rescue Siamese and many are older and have trouble with constipation and some even got impacted which is very painful. Using Royal Canin fibre response has solved this problem and given comfort to the cats with these issues If the problem is not too bad , just sprinkle a handful on your normal Royal Canin food to ease overly dry stools. This food is far better than visits to the vets!
This food is brilliant. It has cured my cats constipation problems completely.
