There are rewards....

Here's a poem:
Felis catus is your taxonomic nomenclature.
An endothermic quadruped, carnivorous by nature.
Your visual, olfactory, and auditory senses
Contribute to your hunting skill and natural defenses.
I find myself intrigued by your sub-vocal oscillations,
A singular development of cat communication.
That obviates your basic hedonistic predilections
For a rhythimic stroking of your fur to demonstrate affection.
A tail is quite essential to your acrobatic talents.
You would not be so agile if you lacked its counterbalance.
And when not being utilized to aid in locomotion,
It often serves to demonstrate the state of your emotion.
Oh Cat, the complex level of behavior you display
Connotes a fairly well-developed cognitive array.
And though you are not sentient, and do not comprehend,
I nonetheless consider you a true and valued friend.
— Lt. Commander Data, "Schisms" [TNG]
I'm still out on the "do not comprehend" business.
Love a Cat, Love a Dog, Love a Frog....if it moves, it grooves.
