Our cat had diarrhoea and vomiting
Our little Tiger had a pancreas infection, which caused very frequent vomiting and diarrhoea. We couldn't get him to eat the medications from the vet. Normal food was too fatty, according to the vet, so he wasn't improving.
This food was lower in fat, well tolerated and he liked eating it. After a very short time our Tiger was better - no vomiting or diarrhoea.
