I had a ferret she was pretty cool. She played hide and go seek with us. And She would go in your poket and get out her food to.
But they smell REALLY BAD.(in some languge there name means smelly feet) That was the worst thing we had to keep her in the landruy room because she smelled so bad. The smell never bothered me to much but my mom. If you get it fixed it will help ALOT with the smell that how she got to move into my room LOL
They make ferret food and sell it at stores and places like that. You can also give them vegs and fruits as treats.
