What age to cats come on there periods?

Cats don't have periods! They are mammals that go into heat, which is a period of time when they are receptive to mating.

Here's the breakdown:

* Cats don't menstruate like humans. They don't have a monthly cycle where they shed the lining of their uterus.

* Instead, they go into heat or estrus. This is a period of time when a cat is fertile and receptive to mating.

* The first heat cycle usually occurs between 4-6 months of age.

* Heat cycles can last anywhere from 3-7 days.

* Cats will go into heat every few weeks, usually during the spring and summer months.

If you have any concerns about your cat's reproductive health, please contact your veterinarian.
