How to deal with a cat meowing every night:

1. Adapt to the environment. Soothe the cat more, play with the cat with toys, feed it snacks, and take it for a walk around the house to help the cat adapt to the environment quickly.

2. Feed regularly. Feed the cat according to the feeding standards on the cat food package. You can also use an automatic feeder to feed the cat and set the feeding once at night.

3. Wait patiently. After a cat is neutered, the male hormones in the male cat's body do not drop as quickly, and they will still meow at night. You need to wait patiently for the male cat's male hormones to drop.

4. Adjust the biological clock. Correct the cat's biological clock, play with the cat during the day, and tease the cat more before going to bed to consume its excess energy.

5. Breeding or sterilization. When a cat is in heat, it will be very restless and its meowing will be different from usual. Sometimes it will even "ouch" randomly. At this time, you should either find a partner for it or send it to a pet hospital for neutering.
