Mouse Nutrition

A proper diet is crucial for the health and well-being of pet mice. As omnivores, they require a balanced mix of grains, seeds, and protein. Providing the right food will help prevent obesity and ensure they get all the necessary nutrients.

Staple Diet: Lab Blocks are Key

The best foundation for a mouse's diet is a high-quality commercial lab block or pellet.

  • Recommended: Lab blocks (like Mazuri Rat & Mouse or Oxbow Essentials Mouse & Young Rat) are the ideal choice. They are nutritionally complete and prevent selective feeding, ensuring your mouse gets a balanced diet in every bite.
  • Acceptable: A high-quality seed mix can be used, but you must ensure your mice are eating all of it, not just the fatty seeds. Supplementing a seed mix with lab blocks is a good strategy.

Because of their high metabolism, mice should have access to their staple food at all times.

Safe Fresh Foods

Offer a small, pea-sized amount of fresh food 2-3 times per week to supplement their diet.
