The first estrus, whispering 1 week is over. Rest 1 month. . . .
The second estrus began to howl 1 week, and rested for more than half a month. . .
Three estrus, rage, howl 1 ~ 2 weeks, rest 1 week. . .
I don't need to give another example. If the problem of longing for spring is not solved, the frequency of estrus will double and the interval will be shortened. There is no peace day and night
In spring and autumn, under the influence of sunlight, cats are more prone to estrus. Fever is less in winter.
