Pet Rats/How to deal with a bully?



I've been going crazy past month or so trying to figure out what to do with one of my bucks. He has become beyond ridiculously aggressive toward his cage mate to the extreme that he tore him open on the side. And I've had him on isolation from that day on, every time he see's his cage mate he puffs up and just tries to maul him. I dont know what to do at this point I dont want to castrate him just yet any tips on how to deal with him? By the way the cage they shared is predominately big enough for both ratties. I feel it's my fault I saw them fighting previous to this attack and never took much notice just thought it was normal rat wrestling.

Thank you so much!

Unfortunately, since your cage is large enough, you don't really have a choice other than to have him neutered if you want the boys to be able to live together peacefully again.  

You didn't mention his age but I'll assume that the boys were rather young when they were getting along and you started to see the aggression when they reached adulthood.  This is fairly common with male rats and neutering will most likely resolve this problem

Please let me know if I can help you with anything else and good luck with your boys.

I can answer a variety of questions regarding adoption and care of pet rats throughout their lifetimes, including questions about their health and well being, temperment, diet, bedding, cages, toys, etc. I will try to answer your questions to the best of my ability in a timely manner and I have an abundant amount of resources to help me to help you with your pet rats. I love rattie pictures, so include pics with your question if you can. You may ask me medical questions, but please be advised that I am not a vet. I may use my resources to answer some medical questions, however, I will need to refer you to your local vet with medical questions that I feel I am not qualified to address.


I have been a huge rat enthusiast for many years. Since becoming a rat owner, I have educated myself in all areas of pet rats from every resource I could find including the internet, books, conversations with local exotic vets, as well as several local rat breeders.

I have a college degree but not in the area of animals. I have obtained my extensive experience and knowlege of pet rats all on my own because in my eyes, pet rats are the most interesting and fascinating creatures you can ever imagine to have as pets. I also am saddened by how mislabeled and misunderstood these amazing and extremely smart animals are by the majority, and my mission in life has become to educate and change as many people's perceptions of rats as I possibly can.
