On the feeding range

Dr John's own guidance gives a 40-80g daily range for an adult ferret, and says it will vary with body weight, activity and environment — it's a starting point rather than a fixed number, so weigh what your ferret actually eats over a week or two and adjust from there.

Why we chose it

It's formulated for ferrets rather than adapted from a cat food, and the protein and fat figures show it. That's worth paying attention to on an animal whose diet is so often an afterthought on the shelf.

— Matt, founder

Full description

Ferret food gets far less shelf space than dog or cat food, which usually means owners end up feeding something that wasn't really formulated for a ferret at all. Dr John built Merlin specifically around the species rather than adapting a small-animal blend.

It's a complete recipe led by poultry meal at 46% chicken, with wheat, chicken fat at 10%, rice at 4%, yeast, potato, linseed at 3%, chicken liver, egg, fish meal and beet pulp at 1%. Crude protein comes in at 37.5% with crude oils and fats at 20%, which is a considerably richer profile than most cat or dog food carries.

On the feeding range. Dr John's own guidance gives a 40-80g daily range for an adult ferret, and says it will vary with body weight, activity and environment — it's a starting point rather than a fixed number, so weigh what your ferret actually eats over a week or two and adjust from there.

Who it's for: owners of one or more pet or working ferrets who want a food built for the species specifically, in a 10kg bag sized for more than a single animal.
