My daughter got it once. No kidding. She was lethargic and run down. Put her on antibiotics and after a few days she was fine.
My guess is that the vets will get it under control. They will need to get her fluids up, and make sure she is getting enough nutrition.
Parvo sucks, but it is very treatable.
The vet said people and cats can’t get it. Should we be worried?
