I have two cats, Aslan & Ender.
Aslan was named after Aslan from the Chronicles of Narnia, and Ender was named after Ender Wiggin from Ender’s Game.
Unbeknownst to us at the time of naming, both names are also Turkish words very fitting to their personalities (Aslan: lion; Ender: rare).
They are brothers, but you can tell them apart based on color (Aslan: orange; Ender: white) and number of teeth (Aslan: >0; Ender: 0).
