If a cat develops lumps in its breasts after giving birth to kittens, it may be because the cat's body's milk is not discharged in time, causing the cat's breasts to swell. It may also be caused by overnutrition in the cat's body. Improving the cat's diet in time can make appropriate improvements. The owner can help the cat express the milk. If the milk cannot be expressed, it may be mastitis. Breast disease is a disease that has a high incidence rate in postpartum cats. It is best to send the cat to the hospital for examination and treatment. The female cat has lumps in her milk during lactation. It usually resolves on its own within a week. If your cat's engorgement worsens, the owner will need help solving the problem. If a nulliparous cat has breast enlargement and lumps, it is because of pseudopregnancy, which is caused by abnormal progesterone in the cat. Generally, the symptoms will subside in a few days.

Solutions to cats’ breast enlargement:

1. The owner can gently massage the female cat’s breasts to help the lumps subside.

2. Apply hot compress twice a day for about 10-20 minutes each time, which will help reduce the hard lumps.

3. Appropriately lower the cat’s diet standards, reduce feeding it food with excessive protein content, and reduce the cat’s milk production to meet the kitten’s normal daily milk sucking needs.

4. The owner can help the cat squeeze out some excess milk to relieve the cat’s milk engorgement.

5. If the cat’s milk engorgement is serious and has not improved, it is recommended that the owner take the cat to the pet hospital to check whether there is mastitis.
