Felis catus is your taxonomic nomenclature
An endothermic quadruped, carnivorous by nature
Your visual, olfactory, and auditory senses
Contribute to your hunting skills and natural defenses.
I find myself intrigued by your sub-vocal oscillations
A singular development of cat communications
That obviates your basic hedonistic predilection
For a rhythmic stroking of your fur to demonstrate affection...
A tail is quite essential for your acrobatic talents.
You would not be so agile if you lacked its counterbalance
And when not being utilized to aid in locomation
It often serves to illustrate the state of your emotion.
Oh, Spot, the complex levels of behavior you display
Connote a rather well developed cognitive array
And though you are not sentient, Spot, and do not comprehend
I nonetheless consider you a true and valued friend...
