Hi, Sarah, and everyone else, We've found two things that really help put weight on our ferrets. First is hand feeding them Bob Church's Chicken Gravy. Second is offering FerretVite as a treat. With this regimen, our Pertwee, who had two adrenalectomies five weeks apart and then went through hell while we tried to get his electrolytes right, gained 70 grams in a single week. Of course, he had lost a tremendous amount of weight, so his body needed to add a bunch quickly. Still, when we've had sick or recovering ferrets before, the gravy and/or Ferretvite has always helped. Oh, and yes, Pertwee is now doing very well indeed. Good luck!
