Supreme small animal food
Supreme is the company behind Science Selective and Tiny Friends Farm, two of the better-known single-pellet small animal food ranges. The defining idea across both is a uniform pellet rather than a mixed muesli, specifically so a rabbit, guinea pig, hamster or chinchilla cannot pick out the tasty bits and leave the rest, which is a genuine problem with old-style mixed feeds.
Why single-pellet food exists
A traditional muesli-style mix looks varied in the bowl, but most small pets will happily eat the sweetcorn and cereal flakes and leave the fibre-rich pellets behind, which means the diet they actually eat ends up nothing like the diet on the label. A single, uniform pellet removes that choice entirely — every mouthful is nutritionally identical.
This matters more for rabbits and guinea pigs than it might seem, because a diet that is short on fibre and long on starchy extras is linked to dental problems and digestive issues over time. A consistent pellet is one part of managing that risk, alongside a genuinely hay-based diet as the bulk of what they eat day to day.
What the range actually covers
Science Selective covers rabbits, guinea pigs, hamsters, gerbils, rats, mice and chinchillas, generally split by life stage, such as junior and adult formulas for rabbits and guinea pigs. Tiny Friends Farm is aimed more specifically at rabbits, guinea pigs, hamsters, gerbils and chinchillas with named product lines rather than a single generic pellet.
Alongside the pellet foods, the wider range includes hay, bedding and a handful of supplements such as vitamin C support for guinea pigs, which do not produce their own vitamin C the way most other small pets do and need it reliably in the diet.

Common questions
- Why won't my rabbit eat a single-pellet food after being on a muesli mix?
- This is a common transition issue, because a rabbit used to picking favourite bits from a mixed feed can be reluctant to switch to a uniform pellet at first. Introduce it gradually alongside the old food and plenty of hay, and most rabbits adjust within a week or two.
- Do guinea pigs need extra vitamin C on top of pellet food?
- Many guinea pig owners do add a vitamin C supplement or vitamin-C-rich vegetables, since guinea pigs cannot make their own and pellet vitamin C content reduces over time once a bag is opened. Check with your vet if you are unsure how much your particular guinea pig needs.
- Is hay more important than pellet food for rabbits?
- Yes, hay should make up the large majority of a rabbit's diet, with pellets as a smaller supplementary part rather than the main event. Pellet food alone, however good the formulation, is not a substitute for a genuinely hay-based diet.
- Can I feed different Supreme products to different small pets in the same household?
- Yes, each product is formulated for a specific species or life stage, so a rabbit, guinea pig and hamster in the same home would each have their own appropriate pellet food rather than sharing one bag. Check the packaging for the intended species before feeding it across different pets.
