Here is how the song goes:

Three little kittens they lost their mittens,
And they began to cry,
Oh, mother dear, we sadly fear
Our mittens we have lost
What? Lost your mittens, you naughty kittens!
Then you shall have no pie.
Mee-ow, mee-ow,
We shall have no pie.

Three little kittens they found their mittens,
And they began to smile,
Oh, mother dear, see here, see here,
Our mittens we have found
What? Found your mittens, you good little kittens,
Then you shall have some pie.
Mee-ow, mee-ow,
We shall have some pie.

Three little kittens put on their mittens,
And soon ate up the pie;
Oh, mother dear, we greatly fear
Our mittens we have soiled
What? Soiled your mittens, you naughty kittens!
Then they began to sigh,
Mee-ow, mee-ow,
And we began to sigh.

Three little kittens they washed their mittens,
And hung them out to dry;
Oh! mother dear, look here, look here,
Our mittens we have washed
What? Washed your mittens, you good little kittens,
But I smell a rat close by.
Mee-ow, mee-ow,
We smell a rat close by.
