I have 2 unneutered male gliders. They are both 100 percent brothers. I got the first one I had him for a few months and then I got his brother. Really worried that they could be fighting I do not see any cuts or injuries on them but I do hear them snap at each other and bark. My first1 likes taking treats from the second1 and I have no clue how to stop it. I feel so bad because I want help them out and I don't want to have to separate them but I also don't want either of them to get hurt. I just now recently learned about food aggression and I'm sure that's why the first1 takes treats from the second1 but is that the only problem I could have? I mean can they sense that they are brothers?
