Hello and dooks to all! I've had my Chloe for about a month and a half and she's about 2 months old. How big do female ferrets get on average and at what age are they fully grown? I've been wondering this, because my other ferret, Cassie, is about 9 months old and she's a lot bigger than Chloe. Heidi Chloe: *Jumps around crazily* "Can we go out now? Huh huh huh?" Cassie: *Sighs* "Do I HAVE to go outside with her?" [Posted in FML issue 3677]
