I've had 2 other ferrets in the past. I used clumpy littler and they ate kitten cat chow. They both lived for seven years. Now that I have this little one I am a nervous reck. All the do's and don't's on the internet  has me about crazy. I worry if I give her enough play time. Because she in a cage upstairs and her play area is down in the basement. I know that they can get colds now so every time she sneezes I get worried. I know that I am being bit cautious, but I just never researched as much about them. I just wish that I could relax and enjoy her as I did the others.
 So I am using the horse  pine pellets for littler. Which is cheaper in the long run for ferret and cat. And I buy good ferret food. Maybe it is my age because I was younger when I had the others. But a ferret is my favorite pet....She is just a bundle of energy and fun.
