I've got some cat creature Familiars named Vignette, Tarquin, Nyx, Nightshade and Zephyr.
Some others I like are Jynx, Euphraxia, Verbena, Anemone, Periwinkle, and Gobbledegook. I like old words and names, plant names and nonsensical and fantastical words for Familiars. (Apparently I also love names with weird letters like V, X, Q and Z in them, haha.)
@TheSpeaker I love His Dark Materials! There are some great Daemon names in there. I remember a long time ago when The Golden Compass came out, I took a quiz to find my Daemon and I got a type of lynx... or maybe it was an ocelot... who was named Tarquin. I've loved that name ever since.
