the vet called us today and said they got the fecal results back and he is negative for parasites, so i'm confused as to what it could be that makes him not want to eat? i'm keeping him on his meds for the next 2 or 3 doses as i was told but they had no idea what it could be & neither do i. we bought some reptaid so after his medicine is over would it be okay to give him a few doses of that if he's not feeling better? thanks in advance.
