I have a little orange girl named Logan. When I found her, she was 4 weeks old and I knew orange girl cats were rare, and she didnt, and still doesn't, retract her claws and I love Wolverine from DC Comics and named her after him, Logan was his original name.
All of my pets have pop culture names. Zander from Buffy the Vampire Slayer (Weenie dog), Malcolm from AC/DC (Bearded Dragon), Gavin from Bush (Fat tabby cat) and Stark from Tony Stark/Iron Man (Skittish long haired orange cat)
Think of your favorite band, movie, book, and choose from that :) A character that fits their personality or looks! Maybe Ellen from the show Supernatural, she had a daughter named Joe in the show and that way if she is pregnant you have a name for a kitten if you want to keep any!
Best wishes, the best animals are the ones who find you.
