The reasons why male cats do not eat or drink after sterilization:

1. The cat has a stress response due to sterilization. Because cats are sensory animals, if they are suddenly sterilized, it can easily lead to the cat not eating or drinking. In this case, the owner must pay attention.

2. The gastric motility has not fully recovered after the operation. During the operation, the doctor uses anesthesia on the cat, which will cause the smooth muscles to relax and suppress the appetite to a certain extent.

3. Wound pain leads to loss of appetite. When the anesthetic wears off, the cat will only feel pain, causing the cat to become restless and unmotivated to eat.

4. The cat may be feeling unwell. The cat will start to eat 2-3 days after the operation, but if the cat still refuses to eat, has a fever, and the wound is red, swollen and oozing blood, the cat may be feeling unwell at this time.

5. After sterilization, the cat will be depressed and in a bad mood, leading to anorexia.

What to do if a neutered cat refuses to eat or drink:

1. Feed gradually. Feed some nutritious food first, such as nutritional paste and other foods that are easy to digest and absorb, and then delay feeding dry cat food.

2. You cannot move the cat to feed it. The pain of neutering can be seen in the cat's expression and body. During the recovery period, the cat cannot be moved and taken to a place to eat.

3. Buy some snacks you like. After recovery, give it some nutrition, reward it, and give it some snacks.
