Pets that typically require the most attention are ones that are social and interactive, such as dogs, birds, and certain breeds of cats. Dogs, for example, need daily exercise, mental stimulation, and companionship. Birds need social interaction, mental stimulation, and a lot of attention to stay happy and healthy. Some cat breeds, like Siamese and Bengal cats, are more demanding of human interaction and attention compared to other breeds. Ultimately, the amount of attention a pet requires can vary based on its individual needs and personality.
