To Laura: >I was playing with Trillian today when I noticed a lump under her skin. Can >we say Heart Attack! I am soooo worried... Go ahead and make the appointment, but I certainly wouldn't have a heart attack just yet. Ferrets develop a fair number of benign skin lesions in the ksin, primarily cysts and small tumors, but a paucity of malignant ones. Another possibility is a vaccine reaction. I would suggest removal and submission to a pathologist for diagnosis. Don't let your vet just toss it in the trashcan - this happens often, as many vets have the opinion that"if it comes back, then it's bad and I'll have it analyzed then....". Playing the odds at this point - you don't have a lot to worry about...
