There are dog people and cat people so it is said.
Others say that dogs are just better actors than cats.

Cats

cats have an attitude
and they use it to effect
they hide behind the sofa
and come out when you least expect
if you're stupid enough to invite
one to lay on your lap
they'll treat you like a disease
and go and take a nap
but if you do even worse
and pretend they don't exist
they'll bite you on the ankle
or stick their claws in your wrist.
