I've got two males. Pip, I've had since February. Kylo, I've only had him since July. I did the side by side cage method, and they did fine. No spitting, trying to bite through cage bars or anything. During the first play times, Pip would do the mounting. Now during play times they both try and mount each other. Though, It's not constant. They'll do it here and there. For the past month, I've had them separated in the two story Critter Nation cage. Before I did that, I tried letting there together to see how they'd react, Pip would try and mount Kylo, who would then rear up and try and spray Pip. So I stopped that immediately. But tonight, after deep cleaning the cage, getting brand new liners, I've decided to open up both levels of the cage to them both. Of course, there is the mounting here and there, no severe chasing, no fur flying, no blood shed. They both have their own food dishes, water bottles and hay bins, which they've been eating and drinking out of each others. A couple of times when one tries to mount the other, they stand up and looks like what I'd call dancing. They're standing up and dancing in circles. Is fighting between chinchillas completely obvious? Am I being paranoid? I know that they can decide to fight to the death and it can get grim real quick. They've been grooming each other, little squeaks and kacks while getting groomed. I get involved after a few seconds when they mount, dance and/or kack.
They've been in the open cage together for a few hours now. They're not actively seeking each other out, but I just want to know if they're truly fighting, if it's completely obvious. Does this sound like they're getting along? Oh, and Kylo even humps Pip when he mounts him. I read about trimming whiskers, but have been on the fence about that. I plan on separating them when I go to sleep until this weekend due to me having to get up and get my son ready for school. Any insight, tips, personal stories would be appreciated!
