Sorry, Kay, I just saw your thread.
I hope Nala's ouchie is nothing serious and that she has a restful night.
One of my vets will regret the day he gave me his home number (when Cody was deathly ill) cause I'd never hesitate to call him. I know the waiting period until your vet opens is nerve wracking. My guess is that you're not going to sleep. I'll be thinking of Nala and awaiting good news!
