There is my dog, Oliver Possibly
There are my cats:
Mister Jones aka Baby Jones
I also adopted two cats away from my mother, and she had named them, so they are single-named:
Henry and Boyfriend.
I have nicknamed Boyfriend “Lil-Pigeon”
because he coos, but truly he has but one name.
How many names (not including those little nicknames you apply later) do your pets have?
