I'm glad that Abby cleared the parasites!

To be cautious, you can pick up a container at your PCP's office to go at home and drop off the poop sample to have it tested for parasites etc, or just call and ask for the med to be faxed to your pharmacy... but if you've been washing your hands after cleaning the litter box, I doubt you've contracted anything... especially since you run constipated vs. having diarrhea.
