Two Songs of a Fool

I

A speckled cat and a tame hare
Eat at my hearthstone
And seep there;
And both look up to me alone
For learning and defence
As I look up to Providence.

I start out of my sleep to think
Some day I may forget
Their food and drink;
Or, the house door left unshut,
The hare may run till it's found
The horn's sweet note and the tooth of the hound.

I bear a burden that might well try
Men that do all by rule,
And what can I
That am a wandering-witted fool
But pray to God that He ease
My great responsibilities?

II

I slept on my three-leged stool by the fire,
The speckled cat slept on my knee;
We never thought to enquire
Where the brown hare might be,
And whether the door were shut.
Who knows how she drank the wind
Stretched up on two legs from the mat,
Before she had settled her mind
To drum with her heel and to leap?
Had I but awakened from sleep
And called her name, she had heard,
It may be, and not have stirred,
That now, it may be, has found
The horn's sweet note and the tooth of the hound. 

William Butler Yeats

Literal Interpretation:

Just like the pets viz. hare and cat look to man for sustainance, The man looks to god for his sustainance.
The man feels responsible for his pets care and prays to god to enable him to discharge his responsiblities.
2nd: The man blames himself for his hare running away.

Try reading the poem as if the pets were not animals but friends of the poet.
