Ever wondered what is in your cat’s kibble and what makes it nutritious? When a new food is produced, the recipe is perfected by the manufacturer and is based on the type of diet they are producing and the nutritional requirements of the pets for whom the food is produced.
The ingredients are mixed together to form a soft dough, which is then put through an extruder and cooked for a few seconds under pressure at medium temperatures. Thereafter, it passes through a die, which cuts the kibble shapes. The kibble is further dried to ensure a moisture content of around 10%. Once completely dry and cooled, some products receive a spray coating of vitamins, minerals and fats, if required.
