Solutions for a newly adopted cat that keeps meowing at night:
1. When a cat is scared in a new environment, it will keep meowing. The owner can gently stroke it, hug it, and soothe its emotions in time.
2. When the temperature is low at night, the cat will keep meowing because it feels cold. The owner can cover it with a blanket or put a hot water bottle in the cat's bed to keep it warm. 
3. Cats will also meow when they are hungry or thirsty at night. Owners can prepare cat food and drinking water for them before going to bed every day.
4. Cats will also meow a lot when they are not feeling well. Owners should check their cats for injuries or illnesses in time, and seek veterinary care immediately if there are any health problems.
5. Cats have very sensitive hearing. Noisy sounds outside the window can cause them to meow incessantly. If the owner closes the window and places the cat in a quiet place, it will gradually calm down.
