Where are mammary glands on a cat?

What does a mammary tumor feel like on a cat?

“The most common clinical sign of a mammary tumor is one (or more) palpable masses (nodules) underneath the skin of the abdomen.” If the tumor has metastasized (spread to other areas of the body), other signs may become evident. Your cat may generally feel unwell, eat less, become lethargic, and lose weight.
