Photographer excels in his pet subjects

The studio has taken photos of dogs, cats, rabbits, chinchillas and hamsters. There have also been requests to do photo shoots of pet snakes and pigs.

Zhang's rates have risen significantly, too. Today, he charges between 3,800 ($540) and 5,800 yuan ($830) per shoot, thanks in part to a boom in the demand for pet products in China.

According to Meituan Dianping, an on-demand services platform, the number of pet photo studios in China increased by 291 percent year-on-year last year.

Most of the customers were born in the 1980s and 1990s.
