I was reading a dated article I think from the United Kingdom and the ferret had a hairball the size of a cotton ball but didn't make it through the recovery stage of the surgery. From what I remember something like a vet tech told the lady that pinapple juice would help disolve hairballs. I was wondering if there was any truth to the story and if so how frequent do you give the pinapple juice and in what quantity? I have a female jill that is a shelter rescue and Mickey passes a lot of gas. I have in the past given Marshal farms ferret lax and it seemed to make a difference. I was just concerned if the stomach had a larger hairball if pinapplejuice was possibly a solution and that ferretlax was only greasing the intestine. Bruce [Posted in FML issue 3142]
