Top 7 Maintenance Pelleted Diets for Small Pets in Canada (2025) — Vet-Backed Choices to Maintain Adult Health and Find the Right Fit for Rabbits, Guinea Pigs & Chinchillas

Living World Green Gourmet Toppers is designed primarily as a palatability topper rather than a standalone complete maintenance diet, making it an economical way to increase variety and encourage picky eaters. Compared with Supreme, Mazuri and Versele-Laga it is significantly cheaper per bag but lacks the full, balanced nutrient profile required for long-term maintenance, so its technical and financial advantage is as a supplement to complete pelleted feeds rather than a replacement.

Hagen’s guinea pig pellets provide a reliable, budget-friendly complete pellet option with added vitamin C and wide retail availability, making them a practical choice for multi-pet households or cost-conscious owners. Technically simpler than premium lines, they trade off some ingredient transparency and forage-first formulation for affordability and accessibility compared with best-in-class products.

Science Selective Chinchilla Food (Supreme Petfoods) is a UK-made, timothy-based pellet that emphasizes very high fiber and low fat to support optimal digestive and dental health in maintenance diets. Technically it rivals Oxbow on forage content but often leans leaner than Mazuri’s fortified approach and can be pricier in export markets; however, its meticulous European formulations are prized by owners seeking minimal additives and consistent fiber levels. Compared with value-oriented blends like Versele-Laga or Martin, Science Selective offers a quality-first option that can justify a higher shelf price for owners prioritizing strict dietary composition.

Living World Hamster Food provides an affordable, widely available pelleted option fortified with vitamins and minerals for day-to-day maintenance. Technically it prevents selective feeding like higher-end pellets such as Oxbow, but it is generally a lower-cost alternative with slightly different ingredient priorities versus premium brands like Oxbow and Nutrience.

Versele-Laga is a strong European contender that combines a balanced, complete pellet approach with palatability and practical pricing for pet owners maintaining gerbils long-term. Technically it sits between budget extruded diets and premium lab or clinical formulas by offering a regionally tailored nutrient mix and good availability in Europe, making it a solid value choice compared with more specialized or higher-cost lines.

Supreme Science Selective is positioned as the market leader for degus because it is a purpose-formulated degu pellet with controlled sugars and a balanced calcium:phosphorus ratio designed specifically for maintenance needs, offering a technical advantage over general chinchilla pellets. Although typically pricier than generic options like Oxbow or Living World, its species-specific formulation and documented nutrient targets make it the best choice when prioritizing metabolic and dental health.

Mazuri Rat & Mouse Diet is a research-grade, nutritionally dense pelleted formula valued for tight nutrient specifications and batch-to-batch consistency, which makes it the technical leader for breeders and facilities that need reproducible maintenance nutrition. While typically pricier than pet-market alternatives on this list, its precision and higher protein/mineral control provide measurable advantages for scientific or high-performance breeding contexts compared with more consumer-oriented brands like Oxbow or Living World. For owners needing laboratory-level assurance, Mazuri trades a higher upfront cost for predictable nutrient delivery and reduced variability.
