Cats and dogs are different species and do not develop romantic love like humans do. However, if cats and dogs grow up together from kittenhood or spend a considerable amount of time together, they may form a mutually dependent relationship.
Some cats and dogs will also show concern when the other is anxious or uneasy, such as by approaching or gently rubbing against them. They can form close emotional bonds and relationships, which may manifest as behaviors similar to love and attachment.
