Female cats normally start to go into estrus when they are about 10 months old, but some female cats will start to go into estrus when they are 6 months old. The specific time of estrus needs to be judged according to the actual situation of the female cat; Cats in estrus may experience symptoms such as bad temper, anxiety, increased appetite, howling, and moist and swollen vulva.
Tips:
The first female cat in heat is generally not an adult yet, and its reproductive organs have not yet matured, so Mating is not allowed; it is best to wait until one year old before breeding the kitten, which is better for the kitten's health.
