This was the story her original owner gave!

She came home with her ear hanging off, and gave her head a big shake, and the tip just flew off!

I'm fairly certain as she was an indoor/outdoor cat with the original owner, someone picked her up, shaved her down, saw the tattoo, and clipped off her ear to signify she was spayed, but didn't get it fully there. It's a very clean cut for a cat fight cut otherwise!

Maybe she noticed? She doesn't seem to care! I can rub both ears and she's fine with it!
