Sense Sonnet Pumper

 Ent"ice"ment - LP Zoo

Stanley, the snowy owl, does do

A weigh in voluntarily,

Here at home in Lincoln Park Zoo,

As a healthcare activity.

The keepers know that Stanley will

More likely step onto the scale

If Stanley senses a good chill.

So ice is put there in a pail.

Whereupon Stanley hops right on,

With calculation of his weight,

Doing some math phenomenon

To assure Stanley's healthy state.

Of course Stanley does check the ice

To see if there may be some mice.
