The Stages of Heat Cycles in Cats

Cats live in the wild but are domesticated due to the carelessness of humans who released them into their territory.

The first stage of the cat’s life is called embryonic development, which includes fertilization and implantation, or hatching from an egg.

The next stage is called fetal development, which starts when the embryo implants itself in a uterus and lasts until birth (when kittens emerge from an egg). Naming for this stage comes from when the uterine wall splits open to allow the kitten to enter.

Cats are often considered to be the most fertile animal in the world. With their extreme reproductive abilities, it is not surprising that some people believe in the myth that cats can get pregnant during their periods of heat.

As per scientists, pregnancy can only happen in cats if they are artificially inseminated or when an embryo has survived for more than 60 days after being conceived.

It is recommended that humans avoid interacting with cats during their heats because they are unpredictable. Cats are not the same as for dogs who have a set breeding period.
