All female cats will naturally go through a heat cycle if they have not been spayed. This heat cycle is referred to as estrous and it indicates that a cat is capable of breeding. There are a few key indications that a cat may be in heat and it is useful for cat owners who may be otherwise wondering why their cat's behavior has changed to recognize these things.
What Is a Heat Cycle for a Cat?
An unspayed female cat is called a queen and has reproductive organs that include a uterus and ovaries. These reproductive organs go through a normal cycle, called an estrous or more commonly a heat cycle, that allows reproduction to occur. During a heat cycle in most mammals, an egg is released from the ovaries prior to breeding and this is called ovulation. But since cats are induced ovulators they don't release eggs during estrous until they breed. They do, however, still have hormonal fluctuations, along with some blood vessel engorgement, during a heat cycle that means their body is telling them it's time to breed.
- Urine spraying
- Attention-seeking behavior
- Demanding or pushy behavior
- Rolling on the floor
- Raising hind end into the air
- Wiggling hind end when the back spine is stroked
- Begging to go outside
- Rubbing its face on things
The first thing most people notice about a cat in heat is how much it vocalizes. Crying, meowing, and yowling are all often loudly heard from a cat in heat. These vocalizations are to get attention and let other cats know that they are in heat.
In addition to the noises, a cat in heat will also seek out attention and affection from its owner and other people. They love to be pet and stroked, especially down their backs and hindquarters. When pet, a cat in heat will often wiggle its hind end, its legs may tap dance, and its tail will be held high into the air. It may also rub its face on its owner and furniture excessively to spread its scent.
Other signs that a cat is in heat include it rolling on the floor, begging to go outside (even if it is an indoor-only cat) by scratching at the door and even spraying urine. A cat will back up to a wall or other vertical object, wiggle its hind end, and spray urine to let other cats know it is in heat. A rush in hormones during the heat cycle causes a cat to have all these exaggerated behaviors and they stop once a cat is no longer in heat.
What To Do When a Cat Is in Heat
If you have a cat that is in heat, the attention-seeking behavior can be annoying and persistent. Breeding a cat in heat will, of course, stop the cycle but then pregnancy is likely to result which will potentially leave you with even more cats that will come into heat. Getting a cat spayed is the best way to prevent or eliminate these unwanted behaviors. This will of course also ensure the cat never goes into heat again and avoids the unwanted behaviors that go along with it. Some veterinarians will want to wait until the current heat cycle has finished due to the increased risk of surgical bleeding while others will spay a cat while actively in heat.
