Yes you can eat one that you want to eat. Read the directions. It will state a withdrawal date. That is the days needed for the active ingrediant to be safely out of the animals syatem if you gave the recomended dosage. I do not think your bottle baby has worms. most works are ingested when the animal eats grass and the eggs are attached to the grass. More prevelent after rain. If you are new i would give the animal a Poly Serum shot. help boost its amune system. Find a good vet and good luck.
