Common Diseases in Female Cats: Pyometra, Mastitis, and Mammary Tumors: Prevention and Treatment
Reproductive diseases in female cats are common, especially in middle-aged and older unspayed cats. These diseases include pyometra, mastitis, and mammary tumors, and their development is often linked to sex hormones. The treatment for these diseases usually involves surgical removal and chemotherapy.
I. Pyometra in Cats
Pyometra most often occurs after a cat's heat cycle, and is most common in middle-aged and older unspayed cats.
1. Symptoms
Abdominal enlargement: The cat's abdomen will be noticeably swollen due to the accumulation of pus in the uterus.
Anorexia: The cat will have a decreased appetite and may lose interest in food.
Lethargy: The cat will be drowsy and sluggish.
Vaginal discharge: The cat's vagina will discharge pus, which may be yellow, green, or brown.
Fever: The cat may have a fever, although this is not always present.
Increased thirst and urination: The cat will drink more water and urinate more frequently.
2. Diagnosis
Blood tests: Most cats will show an increase in white blood cell count and a left shift in white blood cells. Some cats may be anemic, while others may have hyperproteinemia and hypoalbuminemia in the later stages of the disease.
X-rays: If pyometra is severe, X-rays may reveal an enlarged uterus.
3. Treatment
The treatment options for pyometra are as follows:
Antibiotic therapy: Choose the appropriate antibiotics based on bacterial culture and sensitivity testing to control infection.
Intravenous fluid therapy: Since cats with pyometra are prone to dehydration and azotemia, intravenous fluid therapy is needed to rehydrate them and treat azotemia.
Surgical removal: Surgical removal of the uterus and ovaries is the preferred treatment option.
II. Mammary Tumors in Cats
Mammary tumors account for 17% of all tumors in female cats. They are most commonly found in cats between 10 and 12 years of age, and are rarely found in male cats. Cats spayed before the age of 6 months have a less than 9% chance of developing malignant mammary tumors, so spaying at a young age is highly recommended.
1. Symptoms
Breast lumps: Small lumps can be felt around the nipples, either individually or in groups.
Nipple discharge: Some cats may discharge milk or pus from their nipples.
2. Diagnosis
Palpation: By palpating the area around the nipples, small lumps can be detected. If only one lump is present, it can be surgically removed and sent for histopathological analysis. The report will help to determine the origin of the lump and distinguish between malignant and benign lesions, which will be helpful for future chemotherapy.
Imaging tests: Chest X-rays can help diagnose whether the tumor has spread to the chest. If pleural effusion occurs, a pleural fluid sample can be collected and examined for cells.
3. Treatment
Surgery: Once a tumor is diagnosed as malignant by histopathology, complete surgical removal of the mammary glands is the preferred treatment option.
Chemotherapy: Post-operative chemotherapy is recommended as an adjunct, and chest X-rays should be monitored regularly.
4. Prognosis
The average survival time after a diagnosis of malignant mammary tumor is about one year. Factors that affect survival time include: tumor size, surgical extent, and histological grading.
Cats with tumor diameters larger than 3 centimeters have an average survival time of 4-12 months. Cats with tumor diameters of 2-3 centimeters have an average survival time of 2 years.
If tumor cells invade the lymphatic vessels, the prognosis is very poor.
III. Mastitis in Cats
Mastitis is most common in postpartum cats and is often associated with excessive milk production or poor hygiene in the cat's living environment. Mastitis is most often caused by bacterial infection, and some cats may experience redness and pain around their nipples.
1. Symptoms
Redness and pain around nipples: The area around the cat's nipples may be red and swollen, and it may be painful to touch.
Fever: The cat may have a fever and be lethargic.
Anorexia: The cat may have a decreased appetite and lose interest in food.
Nipple discharge: The cat's nipples may discharge pus and blood.
2. Diagnosis
Clinical symptoms: Based on the cat's symptoms, a preliminary diagnosis of mastitis can be made.
Hematology and cytology: Further confirmatory diagnosis can be made through hematology and cytology tests.
Bacterial culture: A nipple discharge sample can be collected for bacterial culture to identify the infecting bacteria and select appropriate antibiotics.
3. Treatment
Antibiotic therapy: Choose appropriate antibiotics based on bacterial culture results.
Hand-rearing: If the mother cat is still nursing kittens, hand-rearing the kittens can reduce mammary gland stimulation.
IV. How to Prevent Reproductive Diseases in Female Cats?
Early spaying: Spaying a female cat before 6 months of age can effectively reduce the risk of pyometra, mammary tumors, and mastitis.
Regular checkups: Regularly take your cat to the veterinarian for checkups. This can help to detect diseases early and provide prompt treatment.
Maintaining hygiene: Keep your cat's living environment clean and sanitary to reduce the chance of bacterial infections.
V. Conclusion
Reproductive diseases are common in female cats, but can be effectively prevented through early spaying, regular checkups, and maintaining good hygiene. If you notice any of the above symptoms in your cat, please take her to the vet for diagnosis and treatment as soon as possible.
