What happens when a cat has its period? - briefly
When a cat is in heat, it exhibits various behavioral and physiological changes. These include increased vocalization, restlessness, and rolling on the ground to leave scent marks. The cat may also experience a slight discharge from the vagina during this period.
What happens when a cat has its period? - in detail
When a female cat enters her reproductive cycle, commonly referred to as estrus or "heat," she experiences significant physical and behavioral changes that are part of her natural reproductive process. This cycle typically occurs every three weeks during the breeding season, which is usually from late winter to early fall in temperate climates.
During this period, several key physiological changes occur:
-
Hormonal Fluctuations: The cat's body produces increased levels of estrogen and progesterone, hormones that regulate the reproductive system. These hormones prepare the uterus for potential pregnancy by causing the lining (endometrium) to thicken in anticipation of a fertilized egg.
-
Behavioral Changes: Cats in heat exhibit distinctive behaviors aimed at attracting males. These include:
- Vocalization: The cat may vocalize more frequently, often with a distinctive, drawn-out meow or cry to signal her availability for mating.
- Restlessness: She becomes more active and restless, pacing around the house or rubbing against objects and people.
- Increased Affection: The cat may show increased affection towards humans and other pets, seeking attention and companionship.
- Raised Tail: Her tail is often raised and held to one side in a characteristic posture to signal her receptiveness to male cats.
-
Physical Changes: Some physical changes that owners might notice include:
- Swollen Vulva: The vulva may appear swollen due to increased blood flow to the area, which is part of the body's preparation for mating.
- Discharge: A slight discharge or spotting can sometimes be observed, though this is not always visible and varies among individual cats.
-
Mating Behavior: If a female cat in heat encounters an intact male, she will typically allow him to mount her. This behavior triggers the release of more hormones that prolong her receptive state until mating is successfully completed or the cycle naturally ends.
-
Duration and Frequency: The estrus cycle can last anywhere from a few days to several weeks if the cat does not mate. If she remains unbred, the cycle may repeat every three weeks or so until the breeding season ends.
-
Health Implications: Prolonged periods of heat without mating can lead to health issues such as uterine infections and even pyometra (an infected uterus), which requires immediate veterinary attention.
Understanding these changes is crucial for cat owners, especially those who do not intend to breed their cats. Spaying, a surgical procedure that removes the ovaries and fallopian tubes, can prevent estrus cycles and related behaviors, as well as significantly reduce the risk of reproductive health issues. Consulting with a veterinarian is advisable for determining the best course of action for your cat's health and well-being.
