Re-writing "Dame Trot and Her Comical Cat"

A long time ago there was a witch,
who had a dog, but considered a switch.
While out for the day
they found a cat, a stray.
With a look they decided that to her they'd hitch.

Back in their humble abode,
the witch went into a welcoming mode.
To her furry pals she gave
some milk. And with a wave,
some of her magic she bestowed.

As the sun went down and their hearth warmed
the witch's furry friends transformed.
They got rather big
and started a jig.
And to their hearts' delight they performed.

But when the next day the sun arose,
the cat and dog found that not all of their changes were pros.
The witch asked for their help
and in protest they gave a yelp,
but in seeing her sadness, chores they chose.

The witch went off shopping in town,
then the pals stopped working and sewed a gown.
The dog played a horse
but found the gown quite coarse
and so he bucked the cat and she fell down.

The witch had returned in time
to see the cat get covered in grime.
"You must be careful
or I'll become despairful,"
the witch said before cleaning off the slime.
