Hi, Three months ago, I adopted two ferrets, Monzy and Slinky. Monzy is a 2.5 year old male and Slinky is a 1.5 year old female ferret. They were sold to me as a breeding pair and had been bred once before. Shortly after adopting them, I had them both fixed. Up until around a week ago, they seemed very chummy and happy to hang out with each other. However, over the last week, Slinky (the female) has started to attack Monzy (the male). She starts jumping on him and trying to get her teeth into his neck or body and then tries to pull back and forth as a dog would when trying to break the neck of a smaller animal. There is still a fair amount of dooking with a few cries and screams. Monzy is twice the size of Slinky but is not aggressive enough to really deter her. Monzy tries to run away but Slinky just chases him and continues to attack. This behaviour can last up to 10 minutes and seems to happen once a day. They still hang out with each other when they play and sleep together at night. Slinky has always been the dominant ferret but has never exhibited this type of behaviour before. I'm not sure if this is just natural play for them or if I should be concerned and seperate them when Slinky gets aggressive. A friend suggested that perhaps Slinky is jealous of the attention that I pay to Monzy but I pay an equal amount of attention to both ferrets. The same friend said that this could possibly be the result of a adrenal tumour(?) in Slinky but considered this to be improbable since she is so young. I think it is also unlikely since Slinky acts agressively neither towards myself nor my girlfriend. Anyway, I would appreciate any advice anyone has to give.
