My boys are starting to get a bit aggressive, Odin in particular. I'm not sure if they're acting out due to me not being home all the time anymore (I've had a full time job for a month now), or if they're just hitting that hormonal stage. Has anyone had groups of 3 or more boys stay together successfully through their whole lives without having to neuter? I worry that if I neuter Odin one of the others will step up and start bullying. I also have 5 boys, so I can't really afford to have them all neutered if the vet wants to charge something ridiculous (haven't looked into it yet). If the charge is less than $100 per rat, I could feasibly have one done every month for the next five months, but I worry about the risks involved. Is there any appropriate course of action that I should take or is it just going to have to be a play by ear kind of thing? I just really want my boys to be their fat happy selves forever.
