Man, I have been having so many problems with my boys! For whatever reason, Velvateen and FIevel got in two rather big fights today. I believe it was Velvateen that instagated both times. I haven’t had an issue with them for quite a few months now. Fievel was neutered a little over a month ago. Their last biggish fight was a few weeks before that, as I’m sure Fievel’s hormones were going crazy. 
Since Fievel has been neutered, they have been living together in an xpen (4’x4′) without any problems. Both fights today were in my room outside of the xpen. Lots of hair missing….
I was hoping that after the first fight, they would be fine.. maybe some brotherly aggression? But about 30-45 minutes later, they were at it again.
I have Fievel in the xpen for the night and Velvateen will be free to roam around the room, as he is much better with the litter box and spends a large portion of the day out of the cage anyways. I think he will do better out than Fievel would.
Any ideas as to what this may be? My biggest worry is that if Velvateen did instagate it, maybe he was hurt. I just posted yesterday about cysts that he has on his feet. They are tender to the touch when I put meds on them, but an odd place for Fievel to nip… I have no reason to believe that anything else is hurting him. I plan to take him to the vet in the next week or two, as the cysts aren’t clearing up. I don’t think Fievel is hurting at all either. I’ve checked both of them over a few times now. Velvateen will tolerate me holding him, but Fievel has freaked out everytime I try to hold him since he was a baby, so it’s difficult to tell with him.
Both of their activity levels are the same, their eating is going well- lots of hay- and they drink as much as they have been znd they love to run around the room and binky. The only time I notce Velvateen getting aggressive with Fievel is when Fievel tries to steal his food.. And he only lunges and grunts. :\
Sorry for posting so many issues on here… I think bad things really do come in threes?
