It is very important to follow all the suggestion that have been a made.
Be sure to follow Heather's instructions regarding setting up a 'hospital' type set-up until you have clean fecal tests (poop without worms)
The vet will help you determine this.
Wear gloves when changing the substrate and water dishes --- wash your hands well........before and after.

If you should need it, here is the link to information for Dr Frye that Heather mentioned.
