In essence, a diet that is high meat, high moisture and fresh, will be healthier for your cat, than standard biscuit-based diets.
In fact, recent research[i] showed that cats on a kibble diet vs a raw meat diet had lower gross energy, protein and fat digestibilities, lower microbiota diversity and produced more poo!
A fresh, high protein diet can also help with diabetes, weight control and urinary tract health.
