I have a 4 year old female Chinchilla, named Tweak. I've had her for about 9 months now and she seems quite happy. I've read online that chinchillas like company, so when I found out a friend of mine wanted to get ride of one of his chinchillas I took a chance. I now have a 3 year old male chinchilla named Cody. Cody use to live with another 4 year old male chinchilla and is quite friendly. While Tweak is a little bit territorial, I read online about all the methods used for introduction. I've put them in separate cages, spaced enough for them to smell each other. I've also let them play together with the dust bowl, I keep a close eye on them at all times. Unfortunately, Tweak keeps biting him and pulling out fur, it's been about a month now. I'm starting to get worried, Tweak seems to attack Cody every time and it's always in the same spot, (so he's got a dent in his fur). I dare not use such methods as the smooshed method. I'm I doing something wrong??? I'm really worried about Cody, should I keep them seperate?
