Shandong Lion Cat

　　If a nursing female cat has poor hygiene management during lactation, mastitis can occur due to mammary gland infection. The affected breast will feel hot, painful, red, and swollen, with abnormal discharge. It is often accompanied by systemic symptoms such as fever, weakness, loss of appetite, and may even cause mammary abscesses. The kittens will become very weak due to lack of milk, and if they ingest bacteria-contaminated milk, it may lead to death.

　　Besides early antibiotic treatment by a veterinarian, the sick cat and kittens must be separated, and the kittens maintained alive through artificial feeding. (Source：PetsZone)
