Thank you all for your kind words in regards to my Katie girl.

Steffi N, I'm glad to say that no, Katie will not have to see the white coats.

I had bought the kitties a new brand of treats that I thought they would like. Mooky turned his nose up at them, but Katie enjoyed them. Even though she had only 3 little treats, apparently it was enough to upset her little tum-tum, plus she was sneaking Chipper's kitty food. I guess it was just too much for her.
Bless Kim with her help in what to give her, she has recovered 100%.
