Cats will become vernal in autumn. Except for the period from the autumnal equinox to the winter solstice, cats will be in estrus at other times. This is because if you give birth to kittens in estrus from the autumnal equinox to the winter solstice, the survival rate of the kittens will be relatively low. And it is not easy for female cats to find food, so this is the only time when they will not go into heat.
Tip:
If the cat lives in a warm place and there is no shortage of food, the cat's estrus period will be extended Some.
