The burrowing thing might have something to do with it, @Kferg. Wilbur does tend to nip at Orville's tail during playtime though, which he super doesn't like and makes the same sound we hear when they're supposed to be going to sleep. I guess I'm just worried it's something that would escalate, since it wasn't something they used to do and just has ramped up slowly in the past month and a half.
They have, like, four different places to sleep around the cage area, but I've only a handful of times seen them actually sleeping apart. I have seen that if the one leaves and goes to a different place, the other will follow him a minute later.
I just want ma babies to get along!
I think it will be better when the pouches arrive... we ordered them like 8 weeks ago and they still haven't arrived!! (The vender had said 3-4 weeks but when we told him they still haven't come he was basically like "well, i hope you love them when they do!".... #customerservice) Hoping it's soon.
