Mice are tiny animals with very fast metabolisms—this means they use up energy very quickly! Because of this, they need to eat often to stay healthy. In 2026, we recommend using mouse blocks or pellets as their main food to make sure they get all the right vitamins without becoming overweight.
The Best Main Food: Blocks
Using a block-style food is the best way to keep your mice healthy.
- No Selective Eating: In seed mixes, mice often pick out the fatty seeds and leave the healthy parts. Blocks ensure they eat a balanced meal.
- Healthy Teeth: Gnawing on hard blocks helps keep their tiny teeth from growing too long.

Making Mealtime Fun
Mice are very active and love to search for food.
- Scatter Feeding: Instead of a bowl, try scattering some of their food in their bedding. It gives them something fun to do and mimics how they find food in the wild.
- Protein Treats: Occasionally giving them a tiny bit of cooked egg or a mealworm can be a great protein boost.
⚠️ Important: Dangerous Foods for Mice
Because they are so small, even a tiny amount of the wrong food can be very bad for a mouse. Never feed them:
- Onions and Garlic: These can damage a mouse's blood cells.
- Chocolate: This is toxic to almost all small pets and should be kept far away from their mouse cage.
- Uncooked Beans: These contain natural toxins that are dangerous if not cooked.
- Apple Seeds: These contain tiny amounts of cyanide—always remove them before giving your mouse a fruit treat.
Fresh Veggies
Mice only need a tiny amount of fresh food—about the size of their ear! A little bit of broccoli, kale, or a tiny slice of apple once or twice a week is perfect.
Checking Their Water
Because they are so small, mice can get dehydrated very quickly. Always check their water bottle every day to make sure it isn't blocked by bedding or leaking.
