This is in response to Tanya Stephens' question about weight gain. Our little boy, Dakota, put on close to a pound in the month of September. We became concerned and took him to our vet. He gave Dakota a good looking over and said that he didn't believe anything was wrong with him. I had heard that large weight fluctuations were possible and I figure this is what happened. I would suggest that if you have a good vet just to take your little Izzy in for a look over if you are concerned. $30 isn't a lot to pay for a little peace of mind. Plus, our vet was so happy to see a healthy ferret. He commented that most of the ferrets he sees are sick with one thing or another. Good Luck! Steve [Posted in FML issue 1754]
