What should I feed a little fieldmouse living in my garden?

Question

I've found a tiny fieldmouse living in-between the flower pots in my back garden. What should I leave outside for it to eat and drink?
Does it need some grass or hay to make a bed?
I don't want it to freeze especially now it has started snowing.
Where do you think it came from?
Thanks!!

Thanks to all who provided a sensible answer!! Your comments and tips have been great.... :)

Answer 1

How utterly lovely! Don't bring it indoors, the key to being a responsible nature lover is knowing when not to touch. If you would like to feed it, nuts are a good source of fat and protien. Try a hard boiled egg, too - just cut it into quarters. Seeds, apples and root vegetables are all good choices as they won't spoil and are easy to store. If you cut them up into pieces the mouse can take them back to it's nest, rather than having to eat them in the open where it's vulnerable.
Have fun! :)

Mice are wonderful! It's so cute to watch them eat, with little paws that look like hands. They're a little tiny miracle. I've had many for pets. One experience I had was when I had a little female white mouse, and she got out one day, and then when I caught her she started to my surprise to swell bigger and bigger. She had a whole slew of wild mice babies, as she had mated with a wild house mouse! The babies were adorable. Still it's better to keep your little friend outside, and see if you can make friends. Leave her something good to eat every day, and see if she gets friendlier. A tiny piece of bread, apple, bird seed, alsmost any good food you like yourself. Put it in the same spot every day, and she will get into a habit of coming to eat, and you may make friends. There are many mice in our gardens, we don't see them because they come out at night a lot. Don't worry about her keeping warm, she will find her own material to make a cosy bed in a little nook somewhere. Little animals are special, I'm getting ready to get a baby guinea pig. It's the little things in life that are truely injoyable. Good luck with your little friend! :) arum

if I was you id try and catch her because at this time of year they should be hibernating and if shes awake she will almost certainly die the best thing you can do is catch her and put her in a box that she cant chew through with some hay and put her in a warmish place and she should go back to sleep then in a couple of months let her go, if she doesnt go back to sleep put some water and feed her fruit, veg and seeds.

its like if you find a hedgehog when they should be hibernating you should put them in a box and let them go back to sleep, maybe the mild weather last week tricked her into waking far too early

Answer 4

The rind from unsalted bacon cut into short strips makes a tasty treat and will give the little fellow some useful body fat to keep warm.
A bit of straw might be useful - put some nearby and see what he thinks.

Answer 5

bird seed is always ok for fieldmouse, however don't take it inside, it should be able to survive by itself. A bit of food wont go amiss though

Answer 6

Any seeds and grains, and some fat. Lard is fine. Fat balls with seeds that you get for the birds. Muesli, wild bird food. Some hay and shredded paper for bedding. It should have a burrow somewhere though, it won't survive out of doors.

Answer 7

AAwww sweet, Once i saw a little mouse eating bird-seed and bread with peanut butter on it. Have not seen it again. I think they will eat anything i feed the birds all kinds of food. You are sooo lucky, they are so cute:))

Answer 8

Any type of bird seeds will due but will be careful ,I know its a field mice but it wont s in also. where talking about baby's more then one . feed the little fellow.

Answer 9

He will find plenty to eat on his own...don't worry. Field mice are everywhere..we just usually dont see them unless they enter the house. I never see them outside but I know we have tons of them because I find them in the oddest places in my garage.
