A new study has found that cats can connect with people in the same way as dogs and children. The research, published in Current Biology, suggests the social abilities of cats to form human attachments has been greatly underestimated. The study notes that more cats live with humans than dogs do worldwide. But historically, more scientific research has centered on the social relationships between people and dogs.
The researchers designed experiments similar to methods used to measure human attachment behaviors. For example, other studies have observed how babies react to being reunited with caregivers after being separated for short periods.
About 70 cats were studied. The hehavior of the animals was observed by experts who divided them into two groups.64 percent were judged to be "securely attached" to caregivers, while 36 percent were found to be "insecurely attached." The cats with secure attachments showed several signs of "reduced stress" levels, the study found. These cats were found to be more comfortable and effectively balanced their attention between the person and their surroundings. However, the cats with an insecure attachment showed clear signs of stress. These included shaking of the tail, repeated licking or staying completely away from the caregiver.
She added that the results showed that the level of secure and insecure attachments in cats is very close to those measured in human babies. In humans, research has found that 65 percent of babies are also securely attached to their caregivers. The researchers also were interested in finding out if socialization training would change the results.
But after a six-week training program for the cats, there were no major differences. "Once an attachment style has been established between the cat and its caregiver, it appears to remain relatively stable overtime, even after a training and socialization intervention(干预), "Vitale said.
