Among pet owners, 84% said their pets had mostly good influence on their mental health. About 64% said their pets provided unconditional (无条件的) love and support, while 62% said their pets provided a calming presence (在场) and lowered stress and anxiety (焦虑). Dog and cat owners were especially likely to say their pets were good for their mental health.
"We see the powerful relationship between people and their animals," said Rena Carlson, president of the AVMA (美国兽医协会). "From offering presence and love to lowering stress and anxiety, pets can give us comfort and support."
A recent study by researchers in Australia got the same result. It found that having a dog led children to be more active because they walked and played with their pets. Girls who had a dog exercised 52 more minutes per day than those who didn't.
However, pets can also cause anxiety to owners, especially when it comes to the animals' health. More than half of pet owners were worried about their pets having health problems, growing older, or passing away. Many people also tried their best to arrange (安排) pet care when they travelled.
47．What animals were the second most common type of pets according to the survey
48．List at least two facts that pets are good for people's mental health.
