I'm glad I decided to hold off on taking Lexi to the vet, she seems to be gradually getting better and eating more. I've gone back to her old food and I've been mixing it with the wet. She gobbled down all of it this morning.
She has picked up a little as well, last night she even was playing with Lucy.
Thanks again for the advice.
Now I've read in a couple places on the internet that garlic is good to help ease the stomach and kill bacteria, was thinking of sprinkling it on her food. Thoughts?
