Why does my cat cry at night and how can I help them stop?

Cats may cry at night due to various reasons such as loneliness, hunger, or medical issues. To help them stop, ensure they have enough food, water, and toys to keep them entertained. Providing a comfortable sleeping area and spending quality time with them during the day can also help alleviate nighttime crying. If the behavior persists, consult a veterinarian to rule out any underlying health issues.
