If cats of the same sex are howling at each other, they may be arguing, fighting over food or territory. In this case, the owner needs to intervene to prevent the cats from fighting and getting injured.
If cats of different sexes are howling at each other, it means they are in heat and want to breed. If the owner does not want to have more cats in the house, it is recommended to have them spayed or neutered as soon as possible to avoid future problems!
