Well, you won't know until you try really. I bonded my 2 boys about a week ago and they took to each beautifully. Everyone (not on here) told me I couldn't do it, it wouldn't work, males can't live together blah, blah, blah.
Well, I did and they can - ha!
Give it a shot, just supervise them constantly for at least 48 hours. When I did it I didn't leave the house the entire weekend.
Like I said, you won't know until you try.
Good luck!
