On the pellet shape

Because every piece is the same, a guinea pig used to picking favourites from a mixed bowl may take a few days to accept it — that's a change in behaviour worth expecting, not a fault in the food itself.

Why we chose it

A single-shape pellet is the actual solution to selective feeding, not just a claim on the bag — there's nothing left for a guinea pig to sort through. Added vitamin C at a stated level is also worth having, since guinea pigs can't produce their own.

Full description

Give a guinea pig a bowl of mixed shapes and colours and most will eat the bits they like first, leaving the rest — which is the entire argument for a food where every piece looks the same.

This is a monocomponent, fully extruded diet: every pellet is identical, so there's nothing for a guinea pig to sort through and discard. It's built around a stated protein level with added vitamin C, since guinea pigs, like people, can't make their own.

Monocomponent, fully extruded — every piece is identical
Protein 15%
Vitamin C added at 800mg/kg
Contains linseed, a source of omega-3 and omega-6
No added sugar or artificial colourants
10KG bag

On the pellet shape. Because every piece is the same, a guinea pig used to picking favourites from a mixed bowl may take a few days to accept it — that's a change in behaviour worth expecting, not a fault in the food itself.

Who it's for: guinea pig owners dealing with selective feeding, or who simply want a monocomponent diet with a stated vitamin C level rather than a traditional mixed bowl.
