Mia, the third

Our Mia's a cllimber, we find,
And a hider--both in and behind--
And she's eating her grub
Giving fingers a rub
And waiting to be unconfined.

And, meanwhile...

Outside on the landing is Ozzie
Who' lurking and listening, because he
Would woo her with flowers
And serenades for hours
And wants a sweet end to this story.
