How do you make your cat go into heat?

All female cats (or queens) that have not been spayed will come in heat (or estrus) at stages in their lives. This may happen from as young as the age of 4 months and recur seasonally (usually summer seasons with more daylight).

The cat stays in heat for normally 4-6 days and during the summer season will come in heat again every 2-3 weeks. These periods may vary widely. The cat will come out of heat and the cycles will end once the cat has mated or the season ends. After giving birth a female cat may come in heat again in as soon as 7 days although this usually happens after about 4 weeks.
