Chicken, lamb and beef arrive from named British farms; salmon from a Scottish fishery.
Slow-cooked in small batches below 90°C, the way you would at home.
Kibble and biscuits go through the oven; chew sticks are rolled and air-dried.
A sample of every batch is checked in the lab before a single bag is filled.
Bags, tins and jars leave London for shops, vets and groomers.
