Medical Benefits Female dogs and cats can get cancer in any part of their reproductive system. This is a picture of a mammary gland cancer.
Mammary glands are where the puppies and kittens get milk from their mothers.
Female dogs and cats can also get a really nasty gross infection called a pyometra that causes the uterus to fill up with pus. The uterus is the place in the animals body where the puppies or kittens stay until they are born. This is a picture of a uterus that was taken out of a female dog that had a pyometra. You can see how big it is. You can even see the pus leaking out of it on one side.
