What to Look For in Rat Food
When choosing food for pet rats, consider these important factors:
Protein Content
Adult rats need moderate protein levels (14-16%). Higher protein (18-20%) is appropriate for young, growing rats or pregnant/nursing females. Too much protein can lead to kidney issues in adult rats.
Lab Blocks vs. Pellets
Lab blocks are uniform, compressed blocks that prevent selective eating and ensure complete nutrition. Pellets serve a similar function. Both are preferable to seed mixes, which encourage rats to pick out favorites and leave essential nutrients.
Fiber Content
Rats need adequate fiber (10-15%) for digestive health. High-fiber foods help maintain gut motility and prevent gastrointestinal issues. Timothy hay can be added for additional fiber.
Fat Content
Moderate fat content (4-6%) is ideal. Higher fat can lead to obesity and health problems. Avoid seed mixes as primary diets, as they're typically too high in fat.
Ingredient Quality
Look for foods made with high-quality grains, proteins, and natural ingredients. Avoid foods with excessive fillers, artificial preservatives, or low-quality by-products.

Remember that rats should have access to food at all times, as they eat small amounts throughout the day. Supplement their diet with fresh vegetables daily, including leafy greens, carrots, and other rat-safe vegetables. Provide fresh fruits as occasional treats, and ensure unlimited access to fresh water. Avoid seed mixes as primary diets, as they encourage selective eating and can lead to nutritional deficiencies.
