I think ‘drama queen’ is on every cat’s resumé. Hope the poor gal feels better soon! Maybe she and sis were playing a bit rough when you weren’t looking. I know Firbank got his eye scratched (nothing major, just some eyedrops at the vet’s) by an over-enthusiastic Harpur when they were rasslin once.
The book I read to learn about photography recommended that when you think you are close enough to your subject, get a bit closer. Seems to have worked here.
