The reasons why a cat doesn't meow during the day but howls incessantly at night may include:
1. Cats sleep most of the day, but may howl at night due to excess energy.
2: Cats in heat will attract mates by making noises, especially at night.
3: Cats may howl at night because they are lonely or bored, seeking companionship and interaction from their owners.
4. Cats will also howl when they are hungry, thirsty, or need to relieve themselves at night.
To address these issues, it is recommended that pet owners spend more time playing with their cats during the day, provide sufficient food and water at night, and consider spaying/neutering to reduce meowing during estrus.
