Recently a group of photos of Siberian tigers became popular on the Chinese internet.
These pictures of Harbin Siberian tigers show obese tigers, that look like they were filled with a balloon. Harbin Municipal Tourism Bureau said that now, more people than in the past are visiting “Harbin Tiger Forest Park”. Previously only Harbin people used to visit the park and because of increased tourists, there was also an increase of food intake, so the tigers have become "fat tigers". "Harbin Daily" reported that many visitors of Harbin Tiger Forest Park, think the tigers were so fat and many netizens posted comments like "I may see a group of fake tigers”; "These are orange fat cats!"; “Usually in zoo, animals are starving to death, here the heavenly tigers, are fat like pigs”.
These docile animals feel satisfied with the level of food, they don't show any sign of aggressiveness. For humans, as well for many mammals, the gut is a second brain. Brain and gut are connected by an extensive network of neurons and the brain-gut axis provide constant feedback. Some hormones produced by the endocrine glands, act on both organs. The intestinal well-being is reflected in the body, brain, and mood, as well as intestinal problems can create forms of stress, negative emotions or aggressiveness.
