How long are female hamsters in heat?

Female hamsters are in heat, also known as estrus, for approximately 4 days every 4 days.

It's important to note that this is a general timeframe, and individual hamsters may experience slight variations.

Here's a breakdown of their cycle:

* Estrus (Heat): 4 days, during which she is receptive to mating.

* Diestrus: 3 days, where she is not receptive.

* Proestrus: 1 day, leading up to estrus.

* Metestrus: 1 day, following estrus.

This entire cycle repeats every 4 days.
