My 2 beardies are 4 year old brothers & have lived together since birth. They are the best of friends & I've never seen them fight or show any signs of aggression towards each other.
When it comes to cuddle time I haven't had a problem yet. I put both of them of chest & sometimes they'll both stay there until I move them (I've slept with them on me for 7 hours one day). Other times Snuggles will cuddle for a few minutes & then leaves me & Legless while he runs around the house like crazy. He'd much rather do that! Legless meanwhile, will happily cuddle up to me forever...
I'm always really careful to give them the same amount of kisses & mummy-talk so they don't feel left out. And before I put them to bed at night I bring Snuggles back for another hug. They cuddle up to each other & then fall asleep on my chest all cosied up. If they don't get their sleeping cuddles, they
black beard me the next day to let me know they're not happy :-x
I know most people will tell you that 2 beardies can't be housed together (jealousy, fighting etc), but from my experience, some can be. It depends on their personalities. Just remember to show them equal love so you can't bred jealousy between them..
Here's a few photo's of my babies hugging. They're so cute!
