Our kibble size for cats is the following:
Kitten: 4-6 mm width & 3-4 mm height
Adult: 9-11 mm width & 4-6 mm height
Senior: 7-9 mm width & 4-6 mm height
Because we work with natural and fresh ingredients, including fresh meat and fish, the size of the kibble is never 100% the same with every production.
