The first question for owners who want to sterilize their pets at home is how old the pet is to undergo sterilization. Scientific research has shown that sterilization before the pet’s first estrus can better prevent the occurrence of many malignant diseases.
Cats and dogs are fertile at 6 months of age. Bitches usually come into heat 1-2 times a year, each lasting about 3 weeks. A female cat can come into heat every 3-4 weeks from spring to early fall after her first estrus, and she may become pregnant again just 10 days after giving birth to kittens.
The gestation period for both cats and dogs is 63 days. Usually the best time to sterilize is before the pet’s first estrus or between estrus, and veterinarians do not recommend sterilization during estrus.
In foreign countries, cats and dogs are currently sterilized when they are 3-4 months old. Some veterinarians believe that the earlier the operation is performed, the better the health and the development of a good character. Spaying and neutering before the first birth usually keeps pets alive and active during their puberty.
