With a female hamster, bleeding could well be coming from the uterus or bladder; Female hamsters can get cystitis, a bladder infection that will require the vet to see your hammy and possibly give you some antibiotics.

Uterine Tumors

He’s Been Cut

Just like people don’t always get along with other people, so it is with hamsters.

Some hamsters are solitary and object to sharing a cage with another hamster.

They will scratch and bite each other and, many times, target the genitals.

Of course, it can lead to bleeding or a raw area around the genitals.

If your hamster has bitten or scratched himself, you should be able to see what is causing his bleeding.

Pyometra – Infection Of The Uterus

Blood found around the tail and bottom of a hamster may well represent blood in the urine.

This could mean an infection in the bladder or infection in the kidneys.

Of course, another possibility is pyometra.

This is a life-threatening condition brought on by an infection of the uterus brought on by hormonal changes in the female reproductive system.

Progesterone is a hormone that is elevated after estrus (heat) for up to two months, thickening the uterine lining in preparation for pregnancy.

Most times, the older female hamsters experienced this infection.

With an open pyometra, you get a discharge of blood or pus from the vulva.

It oozes out when the hamster’s cervix is open.

This kind of bloody discharge from the vaginal area should be attended to by a vet as soon as possible.

A closed pyometra is more severe because the blood accumulates in the body with the cervix being closed. Blood poisoning can occur.

When it comes to treatment, spaying is one way of preventing pyometra.

If left untreated, this infection can lead to kidney failure, toxemia, dehydration, and death in some cases.
