# Ode to spot
# 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 defences.
# I find myself intrigued by your subvocal 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 utilised to aid in locomotion
# It often serves to illustrate the state of your emotions.
# Oh, Spot, the complex levels of behaviour you display
# Connote a fairly well developed cognitive array.
# And though you are not sentient, Spot, and do not comprehend
# I nonetheless consider you a true and valued friend.
