For the surgeon: ligate the vessels as close as you can to the spleen, so you do not damage the blood supply to the stomach (this is the same as in dog or cat spleen surgery, except the ferret blood vessels are smaller). I would also recommend Sevo or Iso only for the anesthesia (avoid the injectables). Expect the ferret to be nauseated after the surgery. Sometimes Carafate and an antacid such as liquid tagamet, zantac, pepcid, etc are needed for the first few days post-op to help with the nausea. A semi liquid diet (Gerber's baby food: "second stage" Chicken with chicken gravy or Hill's a/d) may also help increase the appetite. Keep this ferret isolated from other ferrets for a few days too to help limit the activity level and allow the ferret to heal. Hope that helps and lets us know what the pathology report says.
