Pet Rats/Biting


I have 4 girls in a double story critter nation cage. One is the mother (Spice) & the other 3 are her daughters (Snitch, Bobo & Belle).  Spice had her litter 4 days after we got her & we have had her for 18 months now.

I have lots of hammocks & put assorted items in for interest. They are out for cuddles and play most days.

My problem is with Snitch.  She gets bitten to the point where chunks of skin is removed, & blood is drawn.  She looks skinned in the wound spots sometimes.  The wounds are mostly on her face, but she gets them on her flanks regularly.  I have taken her to the vet for one of her more serious wounds, & have an antibiotic cream.  This has been happening on & off for months.  I have separated her for a week once, but she got depressed & stopped eating.  I don't know who is hurting her.  She is the friendliest girl.

Can you make any suggestions?

Thanks x

Oh my gosh poor girl!  It seems like the only way you will find out who is biting her is to either stay up all night monitoring the cage, set up a camera to record the activity in the cage the entire night, or to put Snitch in the second cage with each rat one at a time for a night or several nights until you determine the culprit.

If you do find out who is hurting her, I would suggest getting another cage the same size as the original and move one of the girls who is NOT hurting her into it with Snitch, and let the other two girls live together in the original cage.   Of course, you should continue play times with all four girls allowed to play together every time, as you would be there to monitor the entire time.

Good luck.  I hope this all works out.  Let me know what happens.  Please don't hesitate to write me again if you need more help.

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.
