She may become unusually affectionate, rub and roll, yowl, tread with her hind feet, or raise her hindquarters when you stroke her back. Keep an unspayed cat indoors and physically separated from intact males—she can become pregnant during her first heat. Contact a veterinarian about spaying and seek advice if heat signs last unusually long or she seems ill.
How do I know if my cat is in heat?
The most noticeable signs of estrus are behavioral, according to VCA Animal Hospitals’ veterinary-authored guidance. A cat in heat may show several of these behaviors:
- Be unusually affectionate or demand attention.
- Rub against people, furniture, or other objects, and roll on the floor.
- Yowl or vocalize loudly and persistently.
- Tread with her hind feet.
- Raise her hindquarters, move her tail to one side, or assume a receptive posture when stroked along the spine.
- Urinate more often or spray, in some cases.
Vaginal bleeding is not commonly observed during a cat’s heat. A sudden change in behavior can be concerning, but the pattern above is characteristic of estrus. Illness signs or unusual discharge warrant veterinary advice rather than being assumed to be part of a normal heat.
How long does a cat stay in heat?
VCA reports an average heat duration of about seven days, with a range of one to 21 days; the individual cycle may be shorter or longer than average. If a cat is not mated, a short interval out of heat commonly follows, but the timing varies. There is no reliable exact date to predict when a particular cat’s signs will stop.

Cats are seasonally polyestrous, meaning they can have repeated cycles during a breeding season. Daylight and environment affect cycling; artificial indoor lighting and tropical conditions can contribute to cats cycling year-round. Puberty begins at about six months on average, though timing varies by individual. These are clinical guidance figures, not guarantees for every cat.
Can a cat get pregnant during her first heat?
Yes. Pregnancy is possible during heat, including a cat’s first cycle. Cats are induced ovulators: mating stimulation triggers ovulation. Keep an unspayed cat indoors and physically separated from intact males while she is in heat; simply supervising her outdoors or relying on a barrier that could fail is not dependable prevention.

What should I do when my cat is in heat?
Prevent contact with intact males
Keep her inside and secure doors, windows, and other possible escape routes. Maintain physical separation from intact males in the household. A cat in heat may be persistent about getting outside, so take extra care when entering or leaving the home.
Ask a veterinarian about spaying
Spaying is the veterinary procedure that prevents pregnancy and ends estrous cycles. Discuss the appropriate timing for your cat with a veterinarian, taking her individual health into account. The cited veterinary guidance does not support a need to let a cat experience a heat or have a litter before spaying.

Do not try hormone treatment on your own
Do not give medication or try a home remedy to suppress heat unless a veterinarian directs you. The Merck Veterinary Manual’s cat-owner guidance on reproduction management describes potentially serious side effects of medical estrus suppression, including uterine inflammation or infection, diabetes, and mammary cancer.

Heat signs continue beyond three weeks
Ask a veterinarian to assess continuous heat behavior lasting more than 21 days. The Merck Veterinary Manual’s guidance on reproductive disorders in female cats says follicular cysts should be suspected in that situation.
