What this symptom means clinically

Metritis is acute or chronic inflammation of the uterine lining and wall, often caused by bacterial invasion or endocrine changes that lead to local infection and immune response. Inflammation may cause fluid or purulent material to accumulate in the uterus and can affect overall physiology through blood or lymph, causing changes in appetite, temperature, or behavior.

🐱 In cats

In cats, metritis is usually related to the estrous cycle and hormonal change. Clinical signs may be subtle, and both open and closed forms can occur.

🐶 In dogs

In dogs, it is commonly linked to luteal-phase endometrial changes, and the disease may progress from local inflammation to uterine fluid accumulation or pus formation.
