My female hamster is bleeding but acting normal. Should I see a vet?

Updated On September 23rd, 2025

Pet's info: Small Animal | Unknown - Small Animal | Female | unspayed | 0.09 lbs

I have 2 female Campbell's Dwarf hamsters that live together. This morning, I realized that 1 of the was bleeding from there genital area (either vagina of anus, I can't tell). She is acting normally, is eating/drinking, and running on her wheel. The bleeding will stop for some time but then start back up again. Do you know the cause of this or how serious it is (do I need to see a vet immediately?)?

When there is red material from around the rear end, it could be coming from the anus, the reproductive tract, or the urinary tract. Additionally, there could be some kind of trauma in the area as well. Seeing blood intermittently is not uncommon with any of these areas. I would recommend that you have Peanut evaluated by a veterinarian. Since she is eating and drinking normally, you likely don't need to rush in tonight, unless you have an emergency veterinarian who is comfortable with evaluating hamsters. If not, it may be better to wait until your regular veterinarian is available. However, if you see a change in Peanut's attitude or appetite, or if her feet start to look more pale in color than pink, I would recommend taking her in immediately. The pale color would be indicative of her losing a great deal of blood. When at the vet, they will clean the area and try to determine where the red material is coming from. There is a pigment that rodents produce, called porphyrins, that can look similar to blood. Your veterinarian can help to distinguish between the two. I hope that Peanut feels better soon!
