Researchers from Spain conducted a survey among hundreds of Spanish cat owners. Almost all domestic cats are curious about new things - almost none of them constantly mark furniture or trouser legs.

According to the owners, cats in dog households purr and play more frequently on average and show fewer behavioral problems. Females were said to be more aggressive, both towards strangers and their owners, while male cats were more sociable and easier to train. Neutered animals were, on average, more playful. Cats that regularly spent more than four hours alone at home were more likely to exhibit compulsive behaviors.
