What is Kitten Season?

Kitten season is when cats are more likely to give birth to new kittens. You can think of this time as a fun and cute time where you can play with fluffy little kittens, and it can also be a stressful time if you decided to take care of stray and abandoned kittens as people are more likely to get rid of a litter during these months.

How Do You Know That Your Cat Is In Heat?

A cat experiences its first heat cycle when it reaches sexual maturity. This usually happens when your cat is about 6 months old, but this age can differ depending on several factors like the weather and the cat’s overall health.

Cats that live in colder regions can have their breeding season as soon as the temperature rises. This can be as early as January or as late as April, depending on the weather, and it lasts till October when the temperatures drop one more time.

In hotter regions, cats can have breeding cycles all year long, and this also means that they’re more likely to produce more litters.

An average heat lasts about 6 days, and if the female cat doesn’t mate during the cycle, it will be out of the heat for a few weeks. This means that an average breeding cycle can be anything between 3 and 6 weeks.

There are several signs that help you know that your cat is in heat.

  • The first sign that owners usually notice is that their cats become too affectionate or even clingy, always trying to rub themselves against their humans or objects around the house.
  • Your cat is likely to become very vocal and annoying during this period.
  • You will see your cat rolling on the floor more often.
  • If you stroke the cat’s back, it will raise its rear legs in the air.
  • Female cats usually urinate on vertical objects like chair legs for marking. They can also spray urine to attract male cats. You can also see male cats from the neighborhood trying to get into your house.
  • In some cases, some cats can experience vaginal bleeding.

When Can a Cat Get Pregnant

A cat usually reaches sexual maturity at the age of 5 or 6 months and will be able to have 2 or 3 litters per year.  While cats usually have an average of four kittens in each litter, this can range from one to 12 kittens.[Source]

As a result, an average cat will have an average of 100 kittens within its reproductive life.

During the heat, a female cat can get pregnant if it mates with a male cat. This is because cats are induced ovulators and will release the eggs from the ovaries when they mate. On average, a female cat will release an egg after three or four mating sessions within 24 hours.

A single female cat or Queen can mate with multiple male cats or Tomcats at the same time. Each mating session can last for a couple of minutes, and the litter might have multiple fathers. After the mating session, the ovaries will be stimulated to release the eggs, and the cat will go out of heat within a couple of days. The pregnancy lasts for 9 weeks on average.

Instead of having litters that you can’t take care of, more veterinarians recommend that owners surgically sterilize their female cats before they experience the first heat, which can happen at the age of 5 or 6 months.

However, if you don’t mind having a litter of kittens that you can take care of, you can definitely allow your cat to have a litter or even two, as long as you’re able to take care of the little kittens.
