TL;DR: Mastitis is a painful bacterial mammary infection in nursing cats that requires veterinary care within 12-24 hours, or immediately if fever or dark skin discoloration occurs. Early intervention is vital to ensure the kittens' milk supply remains safe and the mother recovers quickly.
What is mastitis in nursing cats and what are the common symptoms?
When a nursing mother cat develops hot, hard, or swollen mammary glands, it is often a sign of mastitis. This is a bacterial infection of the milk ducts that can occur during lactation. The condition is painful for the mother and can cause the milk to become toxic or cease production, which puts the health of the kittens at risk.
Is mastitis in my nursing cat considered a veterinary emergency?
- The urgency level for mastitis is typically Medium, requiring care within 12 to 24 hours.
- The situation becomes a High urgency emergency if the cat develops a high fever or becomes lethargic.
- Glands turning a dark purple or black color indicate a critical risk of systemic infection or gangrene.
How does providing a photo of my cat help with the triage process?
- Allows a professional to visually assess the level of inflammation and skin discoloration.
- Helps identify any visible abscesses or abnormal discharge.
- Assists in determining how quickly the cat must be seen by a veterinarian.
- Helps decide if it is safe for the kittens to continue nursing from the affected glands.
Clinical Context (Merck Veterinary Manual)
In nursing cats, mastitis can be acute or chronic, localized or diffuse, and may present with a range of clinical signs from asymptomatic to critically compromised. Affected glands are often hot and painful in acute cases, potentially progressing to septic mastitis with fever, depression, anorexia, and lethargy, leading the dam to neglect her kittens. Chronic or subclinical mastitis may manifest as failure of the kittens to thrive. Diagnosis is based on history and physical examination, with microscopic evaluation of milk revealing inflammatory cells. Milk from each gland should be evaluated in any postpartum queen with systemic illness. A milk sample should be collected for bacterial culture and sensitivity testing to guide antibiotic selection. Broad-spectrum, bactericidal antibiotics should be chosen based on sensitivity, considering their passage to the kittens via milk. Cephalexin (5-15 mg/kg, PO, tid) and amoxicillin/clavulanate (14 mg/kg, PO, bid-tid) are recommended as initial therapeutic agents pending culture results. Hot-packing the affected gland can encourage drainage and relieve discomfort.
