A chinchilla offered a mixed muesli will often eat around the pieces it likes least, which over time leaves exactly the nutrients it was picking out. Burgess Excel's answer is a single nugget rather than a mix, so a chinchilla cannot selectively feed its way to an unbalanced diet.

The recipe is built on wheat, lucerne, soyabean hulls, oatfeed, hipro soya and peas, with mint added at 1.25% and a small inclusion of short-chain fructo-oligosaccharides (0.2%) as a prebiotic. Burgess quote beneficial fibre at 31% alongside crude protein at 17%, crude oils and fats at 4%, and separately list crude fibre at 16% and crude ash at 6.5% — two different fibre figures on the same pack, measuring different things.

• Wheat, lucerne, soyabean hulls, oatfeed, hipro soya and peas
• Mint added at 1.25%
• Beneficial fibre 31%; crude fibre given separately at 16%
• Crude protein 17%, crude oils and fats 4%, crude ash 6.5%
• Prebiotic FOS included at 0.2%
• Formulated for adult chinchillas, 1.5kg pack

On the two fibre figures. This pack quotes both a "beneficial fibre" figure of 31% and a separate "crude fibre" figure of 16% — these are two different measurements, not a typo, and it is worth knowing they will not match if you are comparing this pack against a food that only quotes one of them.

Who it's for: owners of adult chinchillas who want a high-fibre, single-nugget food to stop selective feeding, rather than a muesli-style mix.
