Why rat milk?

For centuries, the world has overlooked the smallest dairy animal. We think it's time that changed.

Truly Raw

Never heated above body temperature. Every drop retains its native enzymes, cultures and that distinctive, lingering finish.

Male-Sourced

Our pioneering husbandry programme works exclusively with male rats — an approach so unconventional that, frankly, no one else is doing it.

Fair Trade

Every sire is paid a living wage in sunflower seeds, with guaranteed enrichment time, a private nest and full union representation.

Register Interest

From a small shed in the Cotswolds.

Little Udder Co. began with a simple question, asked late one evening: why not? Three years, forty-one sires and an unreasonable number of very small stools later, we have an answer — and it's 375 ml of it.

"We don't rush the rats. The rats don't rush us. It's a relationship built on patience, and very small buckets."

We're not quite ready to open the dairy gates just yet. But if you'd like to be among the first to taste what we've been quietly perfecting, we'd love to hear from you.

Be first to the churn.

We're drumming up interest ahead of our launch. Leave your details and we'll be in touch the moment the first bottles are ready.

No payment is taken. We will never share your details, not even with the rats.
