Pet Rats/White rat swollen right foot


Swollen foot
Swollen foot  
HELLO I have a white rat and his leg  has swollen .Ihave tried giving him amoxicillin and ibuprofen for swelling for a few days but it didnt seem to work. He doesnt seem to be in pain or anything. Could it be a tumor or something else that I could give him to treat the swelling. I clean his cage every few days and he lives in a aquarium so he didnt break or sprain it. Thanks if you can help.


Oh no, poor baby.  That does in fact look painful.  Rats, instinctively by nature being prey animals, do not show signs of pain unless it becomes very bad.

This certainly appears to be a case of bumblefoot, which is a severe acute infection rather than a tumor or a fracture.   Amoxicillin is not the right medication.  He needs to be treated with Trimthoprim-sulfa  for at least 14 days.  For severe edema, Prednisone should be prescribed.  Since this condition causes significant discomfort, oral narcotic pain medication such as Torbugesic should be given as well.

Heres a link to a good website describing this condition and you will notice that some of the photos there closely resemble  your boy's condition.

I hope this is helpful and that you will get the meds from your vet and treat him as soon as possible.  I do hope that your boy recovers quickly.

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.
