Sonnenlicht always goes in for annual vaccinations on Halloween (or as close as possible).

The Vet clinic staff absolutely love her. She walks in on her leash and harness. And she lets me dress her up in costumes!
This year she was a Purrmaid. Given her hissy-bitey personality, I made her a shark.

(Note: In the photo, I am not holding her throat...I'm scratching her chin in a comforting manner 'cause she doesn't actually like going to the vet.)

Dad took the photo. You can just see some black fluff that belongs to Dad's cat. They're both due for shots at the same time, but Dad's kitty does not like costumes. Or car rides. My car still smells faintly of cat pee, thanks to her.
