In the perennial battle over dogs and cats, there’s a clear public relations winner.
Dogs are man’s best friend. They’re sociable, faithful and obedient. Our relationship with cats, on the other hand, is often described as more transactional. Aloof, mysterious and independent, cats are with us only because we feed them.
Or maybe not. Researchers recently reported that cats were just as strongly bonded to us as dogs or infants, vindicating cat lovers across the land.
Research into cat behavior has lagged that into dogs. Cats are not social animals, many scientists assumed — and not as easy to work with. But recent studies have begun to plumb the depth of cats’ social lives.
“This idea that cats don’t really care about people or respond to them isn’t holding up,” said Kristyn Vitale, an animal behavior scientist at Oregon State University and lead author of the new study, published in Current Biology. Vitale said.
In a study in 2017, Vitale and her colleagues found that a majority of cats preferred interacting with a person over eating or playing with a toy. In a 2019 study, the researchers found that cats adjusted their behavior according to how much attention a person gave them.
Other researchers have found that cats are sensitive to human emotion and mood and that cats know their names. But scientists had arrived at conflicting findings about whether cats formed attachments to their owners, so Vitale designed a study to more explicitly test that connection.
They recruited owners of 79 kittens and 38 adult cats to participate in a “secure base test,” an experiment commonly used to measure bonds that dogs and primates form with caretakers.
In the experiment, which lasted six minutes, cat and kitten owners entered an unfamiliar room with their animals. After two minutes, the owner left the room, leaving the cat or kitten alone — a potentially stressful experience for the animal. When the owner returned two minutes later, the researchers observed the feline’s response.
About two-thirds of cats and kittens came to greet their owners when they returned, and then went back to exploring the room, periodically returning to their owners. These animals, the researchers concluded, were securely attached to their owners, meaning they viewed them as a safe base in an unfamiliar situation.
About 35% of cats and kittens displayed insecure attachment: They avoided their owners or clung to them when they came back into the room. This does not mean that these pets have a bad relationship with their owners, Vitale said, but that they do not see their owners as a source of security and stress relief.
The findings mirror those found in studies of dogs and human children. In humans, 65% of infants display secure attachment to their caretakers, as do 58% of dogs.
“This result suggests a similarity in sociality in humans and companion animals,” said Atsuko Saito, a behavioral scientist at Sophia University in Tokyo, who was not involved in the new research. “Investigating this phenomenon will help us better understand the evolution of sociality in animals, including us.”
In cats — as in infants and dogs — researchers still do not know all of the factors that shape the caretaker relationship, but it’s likely to be a complex mix of genetics, personality and experience.
It is possible that even more cats are securely bonded to their owners than the new study found, said Mikel Delgado, an animal behavior researcher at the University of California, Davis, who was not involved in the research.
Unlike dogs and infants, many cats spend nearly all of their time inside, so being in a new environment can be a foreign and frightening experience, she said. For some cats, a fearful response to a stressful situation may take precedence over a secure bond with an owner, so the study results may not fully capture the attachments of some cats.
Testing cats’ responses to strangers, rather than to just their owners, might reveal whether cats are truly bonded to a specific person or are sociable toward humans in general, Delgado added.
Vitale and her colleagues plan to delve more deeply into cats’ relationships with people and to test whether specific interventions can help shelter cats form early bonds that help them feel more secure and get adopted more quickly.
“The more we find out about cats, the more we’re seeing that they are social creatures and that social bonds are really important for them,” she said.
