An unexpected visitor

A well spoken Martian came calling last week
He popped in the house for a chat
Though I wasn’t displeased
When he coughed and he sneezed
I was miffed when he swallowed my cat
He said “ I am frightfully sorry,
It isn’t like me to do that
You must think me a hog,
For I much prefer dog,
Or a rodent, like rabbit or rat”
