Get Lactated Ringers Solution, or LRS. Do not get saline. A ferret can only have so much SQ fluids per day. Many people recommend 100ml of water and food a day for a ferret to survive. Of course, you have to take into account what the ferret may be eating and drinking on it's own. All I do is sq 20 to 30ml of LRS and wait for it to subside, see if the ferret stabilizes, if not, I do more fluids. Often it ends up being just 60ml SQ a day, although yes I have had to do 90ml before on very sick animals. Laryssa [Posted in FML 6449]
