Digestive issues in both cats
For years, I fed my cats this food, thinking I was doing the right thing by giving them something with a high meat content. My cats often had stomach and intestinal issues (vomiting and diarrhoea), but I always put this down to their long hair and problems with hairballs.
When my older cat stopped eating this food, I switched both of them to another brand. It's now been three-quarters of a year since the change, and they haven't had any stomach or intestinal problems since!
