Cats generally cannot develop gills after sterilization. A cat's gills are secondary sexual characteristics and generally develop at the same time as the sexual organs are developing. If the cat owner neuters the cat before the cat develops cheeks, the cat will generally not continue to develop cheeks. Moreover, cat cheeks are related to genes. Round-faced cats such as British Shorthair and Exotic Shorthair cats mostly have cheeks, while most other breeds of cats do not have cheek genes. Even if they eat very fat, their faces will still be pointed, such as Oriental cats, Siamese cats, etc.

Changes in cats after sterilization:

1. There will be no symptoms of estrus. After the cat is neutered, the male hormones will no longer be secreted and there will be no symptoms of estrus.

2. The character will become docile and like to stick to the owner. After sterilization, male cats will have less trouble and pain during the estrus period, so their temperament will become docile and clingy, and they will love to act coquettishly towards their owners.

3. Unwilling to move. Some male cats will have symptoms of depression and are unwilling to move. At this time, the owner should spend more time with the cat.

4. The weight will gradually increase. After sterilization, cats will easily gain weight due to hormones, so the cat’s diet must be adjusted to balance food intake.

5. Some male cats may become nervous and irritable due to changes in hormones in their bodies. Cat owners can prepare some toys for their cats. When cats become nervous and irritable, they can play with toys. to provide relief.
