Okay, so I have two ferrets that have been on lasix for about six months for heart and lung issues. We haven't had any problems with it at all, but I mentioned it to my dad's fiance earlier, and she said they might need to be on a potassium supplement or something - she wasn't sure though, she doesn't know about ferrets, but she used to be a nurse and is on lasix herself. The food they eat has some potassium in it - like .7% - and I was wondering if that was enough, or if I should think about getting some extra potassium for them somehow. If I do, I know bananas have a lot of it, so would it be a good idea to mix some banana baby food in with their daily chicken baby food treat? (would rather not use a plain banana, I don't think it would mix as well with the chicken baby food, and it's no good if they won't eat it) I'm going to call my vet and ask on Monday too....
