"The period of heat will last only 3 to 4 days.
So the master, if he is patient, can wait for the end of the problem,
or he can see his veterinarian who will propose a mild vaginal
implant that could stop the reaction right away."
I have a cat and her heat period usually lasts more than 3 to 4 days. It is usually a week long. [Getting her spayed on WED!
]Also, on avg, I think the heat period is more 7-10 days than 3-4 (I wish!). A lot of people have reported their cats being in heat for more than 6 days. JMHO
