Yes, mice can eat carrots. RSPCA Australia lists carrots among the vegetables that can be part of a mouse's daily food, and the Vet Desk calls carrot a useful extra in moderation. A mouse eats only 4 to 5 g of food a day, so a carrot portion is about 0.5 g (0.02 oz): a thin coin-sized slice, a few times a week, raw and washed.
| Safe? | Yes |
| How much | About 0.5 g (0.02 oz): a thin coin-sized slice |
| How often | A few times a week, rotated with greens |
| Best served | Raw, washed, cut thin |
| Watch out for | Tinned or seasoned carrots, too much sweet veg |
Are carrots good for mice?
Yes. RSPCA Australia includes carrots with bok choy, kale, broccoli, green beans and courgette (zucchini) as vegetables that can be given as part of a mouse's daily food allowance. The Vet Desk says carrots can be a beneficial part of the diet in moderation, with vitamin A the standout nutrient, plus fibre.
Raw carrot is also crunchy, and the Vet Desk notes it works as a chew that helps keep teeth at a healthy length. It is not a complete food, though. A good mouse nugget is the base, and VCA says nuggets should make up around 90% of the diet.
How much carrot can a mouse eat?
About 0.5 g (0.02 oz) on days you offer it, which is a thin slice about the size of a 1p coin (a US dime). The Vet Desk puts a mouse's daily food at 4 to 5 g and works out carrot at about 0.5 g. Offer it a few times a week and rotate with leafy greens.
Sources differ on how big the fresh share should be. The Vet Desk gives 15 to 20% vegetables in one place and no more than 10% in another, while VCA keeps fruit and vegetables together to 5 to 10%. We follow the lower figure, because carrot is one of the sweeter vegetables.
How to prepare carrots
- Wash or peel. Scrub the carrot well, or peel it.
- Slice thin. Cut coin-thin rounds or matchsticks, one per mouse.
- Serve raw. The Vet Desk says most mice prefer raw carrot, and it needs no cooking.
- Remove leftovers. The Vet Desk says to take out uneaten carrot at the end of the day. Check the nest too.
Raw, cooked, tinned and carrot tops
| Form | OK? | Notes |
|---|---|---|
| Raw carrot | Yes | Best: crunchy and good for gnawing |
| Plain cooked carrot | Yes | Boiled or steamed with nothing added, cooled |
| Baby carrots | Yes | Same food, just cut a thin slice |
| Carrot tops (leaves) | Yes, a small sprig | The Vet Desk says the tops are safe; wash well |
| Tinned carrots | Only with no added salt | The Vet Desk warns about sodium and preservatives |
| Glazed, buttered or seasoned carrots | No | The Vet Desk says salt and seasoning are harmful |
| Carrot cake, carrot juice | No | Sugar, fat and no fibre |
Who should go easy?
Overweight mice should have greens more often than carrot. The Vet Desk says pregnant, nursing and growing mice may need more food overall, so their fresh portions can rise in proportion.
What to offer alongside
Rotate carrot with greens like kale and broccoli, and a little cucumber. See what can mice eat, the pet mouse diet guide and our pet mouse care guide.
Carrot questions
Can mice eat carrots every day?
They can have vegetables every day, but we'd rotate carrot with greens rather than give it daily. RSPCA Australia lists carrots among daily vegetables, and the Vet Desk advises rotating fruit and vegetables. Carrot is one of the sweeter options, so a few times a week suits most mice.
Can mice eat carrot tops?
Yes, a small sprig. The Vet Desk says carrot tops are safe for mice. Wash them well to remove soil and any residue, shake them dry, and offer a sprig about the length of your fingernail. Remove what isn't eaten by the end of the day.
Do carrots help a mouse's teeth?
They help a little. The Vet Desk says raw carrot can act as a chew that helps keep teeth at a healthy length. Hard nuggets, safe wood and cardboard do most of the work, so keep those in the cage all the time.
