There is currently no research that can confirm that cats will suffer from depression after being neutered. After the sterilization operation, the cat's sex hormone levels will slowly decrease, and the effects of sex hormones on the brain nerves, such as estrus behavior, maternal behavior, etc., will be significantly weakened after the operation. However, there is currently no data showing that sterilized animals will have long-term depression. However, sterilization has a positive impact on the psychology of cats. For example, they no longer need to bear the pain of being in heat, and they no longer have to endure the inner anxiety of wanting to have sex but having no partner. On the contrary, the cat is more lively and obedient than before, which far outweighs its negative effects.

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.
