i agree with evryone who has been positive in there replys, ask any question you want no matter how daft or obvious the answer may be, thats the fun of learning,let them laugh, i aint got no ego to fuel, i just want the answer.
regarding only haveing one ferret, i have an albino jill who is 7 now, she lives by herself, she will not mix however many times ive tried, always ends in fighting or she sulks, she is a good worker,never bites, and i would truast her with anybody, an absolute jem, but i do agree it costs no more to keep 2 than 1.
