    A total of 34 Chinese cities with a combined population of nearly 300 million took park in a pet adoption day at the weekend, promoting the adoption of rescued stray (流浪的)animals.

    The live broadcast of China Pet Adoption Day events in Shanghai, Beijing, Chengdu, Guangzhou, Hangzhou, Nanjin, Qingdao, Tianjin and Xi'an was watched by 562,000 people.

    From Urumqi in the far northwest to Fuzhou on the southeast coast, people gathered to raise awareness of animal care and to help stray find loving homes.

    Sun Quanhui, manager and senior adviser of World Animal Protection, said, “Planet Earth is not only home to humanity but also a home that we share with other animals. It is mankind's duty and important to treat animals kindly in a civilized society.”

    As China's population becomes richer, pet ownership has increased rapidly, but problems, such as pet abandonment and cruelty, are also growing.

    In recent years, more and more adoption events have taken place all over the country, which indicates an awakening of the Chinese public consciousness to animal protection.

    “Adopting a pet instead of buying one has been gaining a wider acceptance.”

    American Edward Dumpe, who has been working on designs for stray animal shelters in Beijing, said, “It surely sounds super sweet and I have no doubt that it must have been the result of great efforts.”

    “I think it is a good step in the right direction, and should be taken as evidence that Chinese society is becoming more aware of stray animals who should be taken care of and treated with respect.”

    In real life, “Rabbit-eating Carrot” is fashion designer who has created clothes embroidered(刺绣)with slogans(口号)such has “Please adopt a pet” and images of her cats, with all earnings going to the Qiming Small Animal Protection Center in Sichuan Province.

    “I didn't know that there were events like this in China. This is fantastic. Impressive.” Said George Philippe, a french living in Beijing and father of two, at an event in the capital.
