Hola! I am a one month subscriber to the FML but this is my first posting. I have two 6-month-old sable ferrets. Our male is Mordecai and our female is Cassie. I also have a fourteen-year-old cat who isn't too thrilled about discovering ferrets. We just bought a Ferret Sleep Sack from Sheppard & Greene Pet Products. I was very interested to find that our new sleepsack is "...very similar to the sleep chambers found in ferret burrows in the wild." I am so glad that my ferrets now feel so much closer to their roots:) On the hissing thing. Our ferrets learned hissing from our cat who hisses and bats at them.(The cat is declawed). They use it to get us to play with them and as a signal to each other. Cassie also looks you dead in the eye, gives you a hiss, and then struggles to get away when you scold her. The cat also gets a large number of hisses aimed at her. Cassie also licks tubs. It hasn't bothered her so far. It is just a little wierd taking a shower with a ferret.
