Pregnant Queen's Mammary Hyperplasia

Mammary hyperplasia in pregnant queens may be caused by endocrine disorders in the body. Long-term administration of hormone-containing foods due to frequent reproduction or non-reproduction of cats causes hormone disorders, which stimulate uterine diseases and mammary hyperplasia. Cats in heat have lower immunity and resistance, making it easy for bacteria to enter the uterus and cause infections, such as endometritis and pyometra. These diseases may lead to mammary hyperplasia.

How to Check Pregnant Queen's Mammary Hyperplasia

Tissue examination can be performed using mammary biopsy to differentiate between mammary hyperplasia and tumors. The clinical features of feline mammary hyperplasia are rapid and abnormal proliferation of mammary tissue. Microscopically, both interstitial tissue and epithelial tissue show hyperplasia. The treatment of mammary hyperplasia involves removing the progesterone source and performing ovarian-uterine resection.Usually, mammary hyperplasia subsides a few weeks after surgery.

What to Do with Pregnant Queen's Mammary Hyperplasia

Terminate the pregnancy, perform ovarian-uterine resection, and the surgical approach is usually lateral rather than median, due to the large mammary glands. After a few weeks of ovarian resection, mammary hyperplasia subsides. If abnormal mammary tissue hyperplasia causes inadequate blood supply and necrosis, or if mammary hyperplasia does not improve after removing the progesterone source, mastectomy should be performed.

How to Care for Pregnant Queen

A pregnant queen's temperament is very unstable during pregnancy, so it is best to reduce playing and teasing with her. If there are other pets at home, it is recommended to separate them to avoid mutual roughhousing and causing the queen to miscarry. The nutrition of early pregnancy should be slightly increased to allow the queen's weight to rise steadily, with a heat requirement of about 100Kcal/kg/day. Do not over supplement nutrients, as this will make the kittens larger and prone to difficult labor for the queen.
