Tara Wheeler, what are you waiting for? Go for it! If F.M. is so mellow, you probably don,t have anything to worry about, especially if they're close to the same size. You should always introduce new ferrets in the open (not so threatening and plenty of places to hide). There will probably be lots of talking and scurying about, and ,yes , some initial fighting (that domimance thing). Don't let this discourage you though. You may even see one drag the other around by the neck (that domimance thing again). Let them do their thing and only intervene if you think its out of hand (screaming going on). If all goes well, try putting them in the cage together. If you do have to break them up on the first meeting, don't give up. Try it a few more times. If they're still fighting, you have a decision to make. If you really don't want to keep them in separate cages, you can try putting them in the cage together for a little while anyway. Sometimes the close quarters speeds up the resolution. I have had this method work in my favor. I had a new female spayed and my older male would terrorise her when I put them out together. I really didn't have the money or the wish for a second cage, so I threw them in and let them work it out. They are cuddle partners to this day. Good luck, and may the force be with you!
