So we took Virgil to the vet on Saturday and not only does he have one kind of worms, he has two kinds. So he had medicine for the first one on Saturday and will have medicine for the other type on Tuesday. The good news is that I haven't seen any gross worm parts in the bed since he had the medicine for the first one. He gets to go back on October 4 for a follow up and his next set of kitten shots. Oddly he seems to be biting a bit less now and he is eating less. We have to be sure to keep them all flea free to prevent the worms from coming back, so we have all of them on Frontline at the moment. It seems to work because I haven't seen any sign of fleas.
I will update after the second worm medicine.
