Selective Science Selective Guinea Pig Food

A guinea pig offered a muesli mix will often pick out the tastiest pieces and leave the rest, which over weeks can leave it short of exactly the nutrients a mix was designed to provide. Supreme Science Selective's Guinea Pig Food solves that with a single nugget rather than a mix, so there is nothing to pick around.

The recipe is built on alfalfa meal, whole wheat, wheat feed, soybean hulls, soybean meal, flaked peas, linseed and sugar beet pulp, with fennel seeds for palatability and dried dandelion among the ingredients. Crude protein is 16%, crude fibre 15%, fat content 4% and inorganic matter 6.5%, with calcium at 0.8% and phosphorus at 0.5%. Supreme describe all the fibre in the recipe as beneficial, and it is supplied across several pack sizes from 350g up to 10kg.

On selective feeding. The whole reason this is a nugget rather than a muesli is to stop a guinea pig eating around the ingredients it likes least — a mixed muesli genuinely can leave an animal short of nutrients it has learned to avoid, which a single-composition nugget makes impossible.

Who it's for: owners of guinea pigs who want a nugget food that cannot be selectively fed around, particularly if a current muesli mix keeps being picked through and left half-finished.
