Lisa, Sorry to hear about Nala's heart. Here are a few things for you to think about and ask your vet. It isn't a good idea to split pills that aren't scored. That means they have a line going down them. There is no way of knowing how much actual medication the ferret is getting. It may not be distributed evenly though the whole pill. I would ask the vet for some liquid Lasix, it is also a diuretic. That way you draw it up in a syringe. If you must split the pills, then try a single edged razor blade. They are the ones with metal wrapped around one side so that you don't cut yourself.
