Snore search

Looking for the source of a snore.

I hear a sound, a quiet breep.
Perhaps it's from my spouse asleep?
No, now he's watching fishing trout.
This time it's not the usual lout.

And the dog, she's looking at me,
so her I guess it couldn't be.
Alas, I'm stumped, then spy the cat.
I never knew she snored like that!
